Let's suppose you don't have access to, but if you open the IP of the site in Firefox instead of the host name, you can access without problems.

Is there an extension or something in Firefox, that before accessing a page, gets its IP and queries the IP instead of the host?

Or maybe a software in Windows?

I cannot use same IP all the time, because the IP changes during the day...

I can't find a plugin, though you can always do it the slow way and bookmark the ip of e.g. , then search the ip and click the resulting link.

But, why can't your computer resolve IP's to domain names? This sounds like a bad problem.

Of course my computer can, but I'm under a proxy and sometimes I get blocked when the hostname belongs to a list ;) and that doesn't happen with IPs... so I need to query the IP instead of the hostname. Your solution is better than mine :) (I always 'ping' the machine, copy & paste the IP and click on Enter) – Oscar Mederos Mar 19 '11 at 8:31
oh I understand now... haha, using proxy is a pain, I remember having the same problem and just gave up. But glad that link was useful. – CreeDorofl Mar 19 '11 at 8:38
