My friend has a problem with his internet provider, because that provider has problems with DNS. So some sites, including Timus, are not available to him because provider can not resolve the address acm.timus.ru ... The only solution to that problem is - using IP-address. But it does not work for Timus... When I try to write in address-bar 194.226.236.105 - I receive the page with "Bad Request".
So, admins, is there any way to browse your site via IP ?

My friend likes your site and would like to have possibility to browse it even now, when there is a problem with provider...

Please help!
Thanks in advance!

Unfortunately, there is no way to access this site by IP.

But you may advise your friend to overcome the problem by adding name resolution entry to local DNS table (it is stored in file 'hosts' situated in system32\drivers\etc\hosts folder under Windows installation folder).
Just add the line
194.226.236.105  acm.timus.ru
to that file and your friend will be able to access Online Judge.

The above solution works for Win2k/WinXP and similar systems. But the same kind of solution can be used for Unix installations too.

Thank you very much!
