Unable to connect to irc on ptcl dsl

hi i have got ptcl dsl in karachi and i am unable to connect to any irc server (DALnet, undernet, freenode etc etc) ... i always get the error "unable to resolve server"

i am not using any firewall softwares and even the windows firewall is turned off. all other internet programs are working fine. please if any one can help ..

OK that specific error made it clear what the problem is. PTCL DNS is returning NIL for irc servers. Change your DNS to google's DNS. If you are not sure how to achieve that, google it. It is just a couple of simple steps.

I just recently received an email from someone with similar name on a similar subject and had checked that IRC works fine for me. So naturally, I am wondering if you are the same person :)
