How to make internet faster - morfizm


Feb. 12th, 2010 10:48 pm How to make internet faster

Comcast DNS servers sux.
I added custom DNS addresses:
- 8.8.8.8 (Google DNS)
- 208.67.222.222 (Open DNS)
and DNS lookups became faster and much more available (no more a few minute lag every now and then, and no more need to powercycle router and modem!)

P.S. As a bonus, no more redirect to Comcast's adware if you mistype an address.
Update: to observe Comcast adware phenomenon, try http://www.google.om/

hm, I'm missing something.. how do you get to adware? if I mistype the address I go to bing (which sometimes knows the right address)

You probably don't have Comcast, do you?
Comcast recently changed their DNS to redirect you to Comcast search page with targeted ads in case of mistype

I have comcast all right, that's why I'm worried:
C:\Windows\system32>ipconfig /all
Connection-specific DNS Suffix . : hsd1.wa.comcast.net.
DNS Servers . . . . . . . . . . . : 68.87.69.150
68.87.85.102

C:\Windows\system32>nslookup 68.87.69.150
Server: cns.beaverton.or.bverton.comcast.net
Address: 68.87.69.150

Maybe you're unaffected? Are you in experiment?! :)

Try www.google.om
(Notice typo in the end)

This definitely took me to ads in the past

yeah that one lands on a comcast page.... weird. other one I tried didn't get there and landed on bing's page instead.


maybe it works like that: if typo is a common one then comcast handles it, otherwise it goes to your search provider.

given the fact that I never mistyped google like that that is entirely plausible.

hehe :)

I used to have:
# 74.125.67.100 *.co
# 74.125.67.100 *.om

in my etc/hosts to work-around this redirect :)

also I wanted to say that four single digits ip address seems freaky :)

I think it's kinda cool!
It's the only IP address (other than 192.168.1.1) that I can actually remember!

what about 127.0.0.1? I use it like every day now :)


I used to remember whole bunch of ip addresses back in school. DNS was really unreliable back then (and slooooow, using ip was way faster).

Oh, yes, of course, 127.0.0.1 :)
Playing with your website?

I can imagine.
I remember the days when I remembered IP of my MUME server and also of a proxy gateway that we used to play it ;)

I do it at work, so it is not *my* website. it has my code though :)

I see :)
Did you deploy a dev. copy of Bing search engine locally? ;)

What are Comcast DNS IPs at your place?
68.87.69.150, 68.87.85.102 do not redirect me to any ad page. IE goes to bing when addreess is wrong.

That's weird.
"jsjsjsj.com" -> bing.com
"google.om" -> comcast
They must use some confidence threshold ...

Maybe for .com they do a look-up from another DNS, but for TLDs they serve themselves?

Verizon то же делает по-умолчанию, но у них есть сервера, которые этим не занимаются (нужно последние цифры заменить на что-то).
Может у Comcast'а тоже есть нормальные сервера?

Гугловские я попробовал использовать на Мауи, но они на удивление тоже барахлили.

Честно говоря, я убрал Comcast'овский DNS не из-за рекламы, а из-за скорости и availability. С рекламой я успешно боролся через записи etc/hosts с моими часто встречающимися опечатками :)

Гугловский DNS барахлит по-другому. По ощущениям: индивидуальные запросы чуть медленее, но зато они все одинаковые, а outages бывают редко и на короткое время (типа секунды...) и для этого можно fall back на другие DNS сервера. Comcast работает периодами: быстро, быстро, быстро, потом бац - немеренно медленно. Outages длительные (минуты) и частые (несколько раз в день). В общем, Google wins.
