Why all the mistrust? Give it a try guys, maybe you'll be surprised. Lol for real. It takes 2 mins to change it and change it back. If you dont believe me and you think your a network gosu.

If your isp has slow lookup times, or times out and has to repeat lookup times, it will affect you Either way, im not giving instructions thats gonna hurt. Just trying to help.
dude the route's will differ because the network traffic has chanced and/or the situation.
The router that made the decision to send me to router n1 now sends me to router n2.
the responce times of the DNS will chance because it was processing 500 request now then 100 before. and the funny thing is the information he is sending back takes a different route.
or is delayed because of a redirect etc.
under normal circumstances it will affect you a couple a ms.
if you have a crappy ISP or their DNS servers are on the frits,
Then yes you can have noticeable results.
still your statement that helps against lag is bullcrap.
lets just end this on this note.

Either way, no matter if you are right or not, that discussion will go off road real fast, the title is misleading. Saying "how to fix your stream lag" means that you actually have a solution that works, rather than "If your isp has slow lookup times, or times out and has to repeat lookup times, it will affect you".

Is there any difference in changing the DNS in the router configuration page compared to changing it in Windows? I have my router settings directly using the openDNS IP
Not really. If you pc is assigned DNS numbers, no matter what DNS your router is using, the pc is going to force the DNS it is set up for instead.
So like if in your router you pppoe and open dns, and you pc is set to DHCP with google dns. You pc is going to force google's dns. I think so anyway.
Unless im mistaken it goes: Pc Primary DNS, Pc Secondary DNS, Router Primary DNS, Router Secondary DNS.
EDIT: Poster underneath me just wants to pick fights as well. This is copy/pasted from OPenDNS website.
You will have to statically assign DNS addresses to each computer to override the DNS settings in the router.

Surely using a different name server might result in getting a different endpoint, and therefore different routing. But the name server has no effect on the routing itself.
Whether or not the endpoint you get from using a different name server is better -- or you get it quicker -- is completely different for every person and therefore you cannot claim that "using Google or OpenDNS name servers will fix your stream lag"
EDIT:
You are mistaken. It takes the hosts file first.

So would this help if you were streaming from a country like Korea? Bad internet routing plays a heavy role in streaming from there and I don't know whether this would help or not.

Ok Dark. So, what we can agree on is OP Subject is not good. I agree, although in the actual post I say it wont affect speeds at all. Your just trying to pick a fight bro.
Im glad you agree, if your isp is at fault (which is generally the case in jtv stream issues) this may help. Thats all I was putting out there. Sorry if subject makes you rage, everything i posted is still true. Lets not make it bigger than it is.

I made an update. According to OpenDNS: You will have to statically assign DNS addresses to each computer to override the DNS settings in the router. So no i think im not mistaken.
I work in a callcenter. If there is a dns issue, regardless if they have a configurable modem or not, if i statically assign dns, thats the dns that gets used.
@DeepBlue2
Most of what I post will affect mostly US and Europeans. Different countries would have to test it to be safe. Because the DNS is being changed, the server your DNS is being used on is Changed. It will all depend on how you communicate with the DNS server. If you can communicate just as fast to this DNS server as you can to your ISP DNS server, than yes you would notice an increase possibly.
Do an ipconfig/all and get what DNS you have. Ping your DNS and look at the results. Do the same to OpenDNS and GoogleDNS. Unless the DNS i posted is slower than to your own DNS, it can potentially help.
What alot of people seem to be arguing about is when I mentioned 'Routing'. Forget I said Routing. Still doesn't change the fact you'll connect to a different CDN server, which means the stream will act differently, for better or worse.

I really don't understand why this would be offtopic. We are discussing a method somebody promotes to help against stream lag. If we where discussing in a strategy thread if this would be a good one, would this also be offtopic?
But back on topic:
I still do not get it.
#1: Yes, the lookup could take a lot of time but why would it? Your ISP (which probably provides your DNS) is in the business of selling you a fast internet connection. If you find out that their DNS is to slow to handle your stuff you would likely leave. Even non knowledgeable people will see this if their friend had never any problems with streaming on a different provider.
#2: Of course you get a different CDN server. For most of your new connections, you get a new CDN server, no matter if you changed your DNS or not. That is exactly what load balancing does.
#A: Also there is a different question. I thought that the recursion would most likely be done on the client side (for short TTL). An example. I want to ask foo.bar.com for its ip address. Now assume nothing is cached in the nameserver I ask my nameserver nach .com's dns, this dns nach .bar.com's dns and this one nach foo.bar.com. Now caching, my nameserver does should really not influence that much. it should cache bar.com but not foo.bar.com if its TTL is to small. The nameserver would just do to much work.
Also bar.com has a high TTL in this case, so my computer caches this and will not ask the nameserver again.
If I am wrong on #A could you please explain why? Any other setup does not really make sense in my opinion.
P.S.: I should probably mention two things. First I am not a specialist in networking but i have a bit of knowledge in it. Second: I don't want to be insulting to anyone because I want to understand why this should help.

You 'network gurus' can fight all day about this and compare your network dick sizes all you want, but I've followed the steps and have been watching 2+ hours of stream and I have seen a considerable difference in the amount of lag I normally get. At first I thought it was just placebo, now I'm a believer.

Changing DNS won't affect your network or bandwidth at all. What it might do is improve loading of intermediate things like ads and tracking servers, which if the flash player does blocking DNS on, could cause your video to freeze. It could also cause you to be routed to a different CDN area which could help if your local CDN is overloaded or otherwise bad.
|
I wouldn't suggest this for mac users. It's weird, when the streams I've been watching today are playing, they are faster, BUT they've also frozen every once in a while and I've had to emergency shut down several times today. Bad news bears.
|
Does this help in only WATCHING streams? Or also when streaming your own stuff?
|
I get what you mean when you are saying that different dns servers can have different lookup times for various reasons, what you have to understand is that the dns does not provide traffic with a routing path. Only a destination.
How you get there or what server in that particular cluster you are connected to might be different from ping to ping but that is because of load balancing. Secondly a stream do not rely on dns traffic for every packet. When you first start a stream it starts a session which removes the need for constant lookup with a dns server. I really don't understand how this would help anyone other than placebo but if I am missing something please care to elaborate.

Just kidding! It was a weird driver I had started using on the same day that was causing the crashes. The DNS thing works like a charm :D

i heard putting salt in your usb port can help, basically salt reacts with the copper connection in your usb port improving your ping. Works best on old usb's, it might also be the gremlins in your computer likes salt.

I will test for a few days if that fixes my telecom-youtube lag, will post results soon. Even if it doesnt help, thanks for putting the time in to help out people. 
Edit: unfortunaly it didn't work.
