ISP Block Some Web Sites

By alashhar ·
in Libya, there is only one ISP and recently it has blocked some web sites such as youtube due to ??????? reasons. anyway some my friends have found a solution which change ISP DNS IP Address to Google DNS IP Address (8.8.8. or OpenDNS ( it is working fine with them,now they can open youtube and other blocked sites. but for me it is not working.

my internet connection statue:

(1)i have Wimax Internet contract
(2)i have Wimax Huawei Internet Gateway
(3)i do not have static IP Address, ISP provides dynamic IP addresses

i have changed IP address configuration in Windows XP to google DNS addresses because there is no option in my Gateway to write manually DNS IP address, i have to write all IP addresses Configuration, which cause the Internet stop working.

anybody can give me logic reason ????

You want a logical reason for what exactly?

Do you mean NOT working? <br>
Once again I'm confused. You didn't answer my other questions either.

I think the second answer was also edited to include "not".

I don't think it would matter how early in the day it is for you.

Proxy avoidance sites

by Mohammad Oweis In reply to ISP Block Some Web Sites

Forget about changing DNS address.
Use Google and search for some Proxy avoidance sites and use these sites to connect you to any blocked site.

Changing the DNS from windows will not work, because its point to your gateway.
It should be changed from your gateway.

By the way, how is the quality of the WiMax connection in Libya, i heard that it was awful in the beginning.

Not entirely correct.

"Forget about changing DNS address."

This does work in some cases, until the government accounts for it, too.

"Changing the DNS from windows will not work, because its point to your gateway."

No, not unless you leave the gateway address in the DNS list. You can break local name resolution by doing this, in fact.

If the router, however, can force some or all types of DNS requests (UDP or TCP, port 53 or 5353) to a particular provider, this will limit or block the effectiveness of changing DNS addresses.

The ISP can still force DNS as well if all these bases are covered.

As well as proxy avoidance, using a proxy yourself may or may not work. Some proxies are blocked as well, so trying different ones may help.

Proceed at your own risk. Don't get in trouble with the government.

After a second thought i think you maybe right about changing DNS, because when you change the DNS and use another one like Google DNS, it will be harder for your ISP to spy on you, and you could avoid there blocking mechanism (not always; because they can use traffic inspection boxes like Packeteer and block it, unless if you use SSL)

About splitting DNS requests, i have never thought that an ADSL router could have a feature like this.
This is cool :)

I'd thought of using OpenDNS servers.

OpenDNS is very good.

by seanferd In reply to I'd thought of using Open ...

My only concern with using OpenDNS in some areas of the world is server location in the case of visiting domains which make use of CDNs.

I'm not sure what the routing would be like from Libya, but requests from there should be routed to London or Amsterdam DNS servers. (Of course, you get really weird routing in the U.S. sometimes, from some ISPs and other ASes more than others.)

But CDNs deliver content based on location of the DNS server, not the user's location, so sometimes delivery from CDNs gets laggy or times out. (Better than no delivery ever, I suppose.) Australians using OpenDNS tend to experience this.

Google DNS, with greater world presence, may be more useful for people residing in some countries. Try-and-see is a good approach. It hardly takes any effort to change DNS servers.
