Opendns vs google public dns vs ISP's ? + other misc dns info.

Finally got around to messing with dns settings in #!. Was hoping to hear what folks here in the #! community have to say about the subject. Experiences good or bad ... any outages, so forth ? Atm opting for google's dns. My findings so far from messing around w it.

ISP's was ok ... Not like it was slow. Just wanted to see if I could eek a bit more out of one of the alternatives.

Opendns ... Think was a bit peppier than the ISP's. But it hijacked my mozilla address bar, no more easy searches via address bar = annoying redirect to opendns results instead. Tried this, that, a few other things and no joy. Soon got annoyed and went with something else.

Google public dns ... Unless it's my imagination, does seem a small boost. Nothing dazzling but something anyway.


Was going to go ahead and share a babbling sorta how to on the topic. But wanted to see what people w more experience with these services think or have to say about it. What are you using folks and how's it been working out for you ? 



Thanks in advance for replies and input.


afterthought: Yep ... yet more babbling. If anyone is going to run off 1/2 cocked w this. Hope you will make/keep copies of the working config files. Seems it's always a good idea to be able to undo something if somebody doesn't like the results. Obligatory word of caution etc ...

Re: Opendns vs google public dns vs ISP's ? + other misc dns info.

I use Google's DNS on all the machines I run or maintain. I've simply never had any problems with it, which i can't say for all the ISP servers I used.

Re: Opendns vs google public dns vs ISP's ? + other misc dns info.

Thanks El,

Coming from you, I'll take that as a big vote of confidence. Always good to hear what more experienced gnu/nixers have to say about something.


(Yep edit) For me couldn't tell much diff in terms of speed between google's and opendns's. Both seem faster and more reliable than the default one from the ISP. At least google didn't try to hijack anything, well at least that I know of anyway. wink


tc El and folks, w let this run awhile and might be back later with the babbling how to. Didn't seem to be a straightforward/recent one on the forums.

Re: Opendns vs google public dns vs ISP's ? + other misc dns info.

I've had bad experiences with ISP's DNS and since moving to OpenDNS, I've not had a single moments hassle. I've never tried Google but from what I hear, it's pretty good too.

Re: Opendns vs google public dns vs ISP's ? + other misc dns info.

OpenDNS works the best for me out of the three. My ISP is abysmal though. Sometimes I've thought of getting an ISDN connection just so I don't lose connectivity all the time.

Thanks mynis01,

It seemed fine to me. I just didn't like it. Seemed to offer more than I wanted anyway. But am all for people trying them all and seeing what they like the best. Definitely thought it was worth sharing.
Since I brought it up felt obligated to do a babbling how to on it. Lol .... one of my painfully detailed by gnu/nix newb 4 gnu/nix newbs postings.

Link to ... better dns servers how to. Would appreciate some people looking it over to make sure I didn't miss something in it.


Viva la gnu/Linux ! n happy computing folks !

Re: Opendns vs google public dns vs ISP's ? + other misc dns info.

There's an open source app called namebench:
http://code.google.com/p/namebench/
It checks out all the dns servers available in your neighbourhood, compares them and gives you a list of recommended ones.

I tried it and the dns servers it suggested seem to have given me a fair speed boost compared with my ISP.

WOWZA, thanks for the share johnraff,

Am definitely bookmarking that puppy. Though am about burnt out on messing with PC's atm. Will no doubt end up playing with that suggestion. Google pub dns is doing me fairly well. In fact going to have to email and plead with Corenominal to bog this website down. The #! forum is already fast anyway, kinda feel a lil whoozy when I visit now. wink

Thanks again John ...

Re: Opendns vs google public dns vs ISP's ? + other misc dns info.

Hah, it's been a while since I ran namebench. It says the best primary DNS for me is 8.8.8.8, and the best secondary is my ISP. It's weird having a good ISP, since my previous one (the state monopolist) was horrible.

I was about to mention Namebench as well unti I saw johnraff had mentioned it is a very nice program.  My fastest (by a lot AFAIR) listed by Namebench was the Google public dns and I've been using it since.

Re: Opendns vs google public dns vs ISP's ? + other misc dns info.

Ran that prog Johnraff was nice enough to share. Got the exact same results as El_koraco.


Goog public dns came in 1st, opendns's 2nd nameserver #2.


Maybe someone else will get diff results though. So mini how to on running that sucker.

I downloaded the namebench prog, created a folder in my /home directory called  miscprog, then cut/pasted the namebench download there, extracted the sucker there, then deleted the download. Went into the namebench folder and clicked on namebench.py to run it.

Posting cuz this is kinda interesting + BUMP. Back up into da top ya go thread. So more folks get the benefit of this junk. Who doesn't want a faster browser afterall ? And we all spent more than a lil time typing out this stuff so back ya go thread, back ya go. big_smile

Re: Opendns vs google public dns vs ISP's ? + other misc dns info.

Here's my namebench results if anyone wants to check them out. My ISP is time-warner/roadrunner, and as you can see from the results, they actually deliberately redirect me to the wrong websites. A couple weeks ago, a new ISP became available in my area and I'll be switching to DSL sometime next week. YAY!!!

Re: Opendns vs google public dns vs ISP's ? + other misc dns info.

One more ... over limit as usual lately, gawds !


But why not babble some more ... Plus gives a reason to BUMP, BUMP, BUMP, lol.

Thanks Tunafish, tried summin similar to that ... didn't work. That looks like it would, the ns=1&g part, looks like something I was missing. Could've gotten around it a bunch of ways. IF I'd wanted to change the way I use mozilla's stuff. I won't and don't think I should have to, to use a service. Supposed to also be able to disable it in the admin dashboard opendns has. Though wondering if you'd then have to stay signed into or what ? Something else I don't like the idea of personally. In my case google public dns servers are faster than the ones from opendns anyway. Am sure that won't be 100% the same for everyone though. We/they have the option of trying them all, running the namebench prog Johnraff included here ... etc.

All for people using/seeing what works best for them. So am not condemning opendns, beyond the obvious ... Which is I got bad vibe off them. Nor championing goog pub service. Google Inc could dry up and blow away for all I care about them. I'd miss some of their free services, wouldn't miss them at all, lol.

Anyway, just more babbling opinions on this stuff. Mainly just wanted to share summin I tried and got good results with for the sake of other #!ers enjoyment. And of course thanks to all the other gnu/nixers who shared  or added stuff to the thread too.


Happy computing. wink

Re: Opendns vs google public dns vs ISP's ? + other misc dns info.

I tried OpenDNS, but I am back to Google DNS. Because OpenDNS also filter some forum, which they think it is hacking related.

Re: Opendns vs google public dns vs ISP's ? + other misc dns info.

Would 1st like to point summin out, a nixer cannot necrobump one of their own threads. No matter how much time has past dang it. Since Vasty closed the other one, am posting newish related babble here. smile

There is potentially a hybrid solution folks can use to achieve even faster dns resolution, sans requests and thusly also eliminate packet transit time. End result properly implemented ? Should by all reasonable standards equate to whatever boost in browserage speeds. Plus as an added incentive, privacy obsessed nixers get to add yet another tactic to their omg ... everybody is watching and out to get me evasion trickbag.

Is completely poss to set up and maintain a local dns server/setup. Which of course means having to periodically sync w an up to date dns server(s) somewhere on the interwebz. However really see no reason why IP's and IP ranges for many things are subject to over frequent changes anyway. Clearly this would result in the aforementioned benefits, at least the theory is totally sound. Haven't felt the need to utilize this kinda thing. Still felt it interesting and worth mentioning regardless. A bit of googling should no doubt tell folks all they'd ever wanna know about it.

Someone who's already been here, done this ... or decides to give it a go. Would be nice if you'd contribute and let the rest of us know what's what. Thanks fellow nixers.

Also yeppers there's already integrated dns type stuff cached various places as well. Though clearly that kind of thing is diff from what am babbling about. For ie: about:config in Fireweasel and any of their newer relatives, search for this sucker > network.dns.disablePrefetch or just the word prefetch and it pops up. Have mentioned my views on prefetch before. Guess going ahead and doing dns resolution for links of visited webpgs isn't so annoying as outright prefetching whole pgs. Still ... just me, I disable both anyway. For my situation it works best me thinks.

Vll! and faster dns'ing and web browserage.

Re: Opendns vs google public dns vs ISP's ? + other misc dns info.

I have recently switched to using google (8.8.8.8) as my nameserver on my Debian & Arch boxes simply for security reasons (ie, in case my cheap-ass router gets pwned).

There are several methods that can be used with Debian -- I have used them all, just in case.©

Re: Opendns vs google public dns vs ISP's ? + other misc dns info.

^ Looks interesting HOAS.

Was more alluding to fiddling w a dns cache (this kinda, sorta), which OS's and/or browsers are doing anyway. Isn't an area of tweakage ever really spent much time focusing on. Domain resolution should be a pretty straight forward process, the idea is to somehow eliminate the need for packets to transit and return to client comp to facilitate web browsing.

Eliminate such, has to result in decreased time, thus logically speed boost to whatever extent. Still makes sense to have a good quality dns server in the mix. Google has much web presence and plenty cash, resulting in fast and quality services, google public dns being one of those. Use it meself ...

Johnraff posted about namebench in post #8 in the thread. If you have the time and feel like playing with it may run it on your system. Many nixers are seriously concerned w privacy. The prospect of someone recording their dns activity not something they find appealing.

Not sure how practical it'd be to actually setup and maintain a local dns server. In terms of privacy, maybe, sorta. Not so sure though, as they're still utilizing the interwebz and kinda consider it almost like a public highway. You can tint the window$ on your car tho or whatever. Am more interested in eeking out some browser speed gain by exploring fiddling with it. For me Google public dns does seem to make things snappier and was confirmed via namebench as faster than the one my ISP at the time provided OOTB.

Really just more weird babble and a random tweakage prospect fellow nixer. smile Also really dorkish, basically if you have a dns server (optimized caching) on your local network, domain resolution time drastically slashed = some speed boost and sorta in ways a privacy enhancement. As the maintainers of whichever dns server someone is presently relying on is taken outta da loop, other than syncing thingy.

Way it works, check local cache, no ... check next listed dns server, still no, next dns server. All fail ... comp user gets the not found screen. Personally wouldn't need many muey mas of the domain extensions. ie: .gov, .edu, country specific blahblahblah. Mostly .com o course and for the few times something outside that's needed. That's why there's more than 1 dns server defined. In which case, biz will take hiz chances.

OMG! ... dispatch the black helo's and vans, some guy just accessed a .gov domain ! Yep ... we got a code red, code red, he's visiting naughtynuns.com again ! Perverted terrorist ... gotta be ! smile

Re: Opendns vs google public dns vs ISP's ? + other misc dns info.

Thanks fellow nixer.

It's all a part of biz's plan to take ova da digi-world ! Sometimes have to type passable person-like stuff, shift folks off balance and thusly the oncoming waves of babble are sure to have more impact.

Aka: Appear weak when ye are strong and vice versa me friend. smile


Dang it ... misc infobit kinda related, as HOAS likely already know's. The blessed Archwiki advises folks to turn off some settings in FF's settings, options>Security tab, block reported attack sites and block reported web forgeries. Wholly agree w them, mentioned before but apparently google maintains those, the blacklist of sites that are checked against, so for privacy minded nixers.

Just another dns thing they may care to be aware of. For me ( someone who doesn't mind flatout using Google's public dns servers anyway.) Interest is in eliminating any additional requests or checks that have to be made against this blacklist, thus regain whatever tiny bit of browserage speed it may involve. Plus those annoying, danger, danger ! Get me out of here warnings are tardtastic imo.


Viva la Archwiki !

Re: Opendns vs google public dns vs ISP's ? + other misc dns info.

Some more after-thought babble junk ...

Really overall this area of tweakage ( spending too much time dorking w dns cache or considering setting up a local dns server) get's bizziez more PITA than potential rating. Though does have potential, approached w intelligence and common sense could definitely be worth some time invested.

As already covered, switching to a better dns server(s) is easy and worthwhile imo. Not so much worth trying to reinvent a wheel though. If someone decides to, plenty of pointers and info. Junk like this.

There for the taking/use of. Do remember people in this forum discussing dns cache optimizing. Of the built in dns configs w/o having to do anything extreme. Depending on what they were going for, increasing dns cache size, how long entries are kept + flushed or shrinking the cache and flushing more often depending on x-nixers preferences.

Re: Opendns vs google public dns vs ISP's ? + other misc dns info.

More misc dns related stuff ! YaY!

Being a dork ... decided to dig around in Firefox's about:config's and look things over. Since this dns dorkishness was on mind anyway, of course searched for the dns in config's search bar. Yep ... interesting looking stuff came up. Hmmmm ... GOOGLE !

And these are noteworthy imo: ( FF v 35.01, just now upgraded to v 36 btw YaY! some more. smile )

network.dnsCacheEntries , obviously the # of dns entries FF keeps, default is 400.
network.dnsCacheExpiration , how long entries are kept, default is 60 (secs)
network.dnsCacheExpirationGracePeriod default also 60 ( secs) to flush the FF dns cache, set it to 0, reload a webpg or restart browser, then set it back to the preferred number.

Setting these to zer0, clearly also how someone would want to go about totally disabling dns caching if desired, shrugs.

Btw: These defaults do not look necessarily sane in biz's opinion and am going to fiddle with them. Again folks ... keep in mind that your gnu/nixy goodness also maintains a dns cache, as well as M$'s poopware too. Seems kinda redundant but whatever.

For me ... set # of entries to 500 ( thinking about much higher. Edit: Well not ridiculously high. Actually prob stick w 500 for awhile.) and expiration and grace period to 36000 = 10hrs. ( also thinking of much higher w these too. ) If anything blows up, cpu melts or RAM overhead shoots off chart, I'll try to update this. smile

Re: Opendns vs google public dns vs ISP's ? + other misc dns info.

Update: Nothing much to report w the above about:config settings. Nothing stands out statswise and considering I'm employing other various config tweaks, can't really even say if it's having any performance impact + or -. Still stuff like this has to be dorked w regardless.
