As imposed by my government, my ISP blocks some sites, like Facebook and YouTube.

The ISP's MikroTik device redirects the blocked websites to a local IP address (192.168.222.66), which says that the site is blocked.

How can I get a list of all sites that are blocked? (I'm not trying to access the blocked sites; I know how to access them, but I just want to get a list.)

I tried some nslookup commands to get the domains given the local IP address, but to no avail.

  • Use a proxy or get a new ISP

  • Try using tracert, it might go to the site and give you the IP before the redirect. Although if it's at the ISP level then I doubt it will get to the site. Jul 14, 2014 at 21:23

    I don't understand the question. Are you trying to find all of the web sites that are redirected to 192.168.222.66 or are you trying to access all the web sites that are redirected to 192.168.222.66?

  • Are you sure it's an ISP, and not some company restriction, or something in your modem/router? If you're sure, then what is showing on 192.168.222.66? (I find it odd that an IP address in the private range is used.)

Using a proxy server is always a good and would most likely resolve your issue. Another potential option is to change your DNS servers to 8.8.8.8 or 8.8.4.4 (Google Public DNS) and see if that works. If neither of those options work, most likely due to packet inspection from the provider, using a Encrypted VPN should work.

One thing you can try is just hitting the secured version of the site.

https://facebook.com or https://youtube.com

Most filters only block based on domain names and since the domain name is going over ssl the ISP's filter will only see an IP address pass through the system.

You can also use something like ultrasurf if you want to go the proxy/vpn route.

  • Really? The "domain name goes over SSL"? Not in my experience. I have a DNS filter set up on our network; it does not work to bypass a DNS filter by prefixing https:// to it. However, a VPN/Proxy could work.

  • Indeed, it won't stop DNS filtering, but I didn't even know such is used, as DNS filtering is easily circumvented using a HOSTS file? Once the IP address is known, the host name is sent to the web server over SSL and can no longer be sniffed.
