first, the first public release of mIRC was in 1995 ..
but at any rate.
not every city has local irc servers
for an updated server list of the main servers that have been entered into mIRC download the newest servers.ini file from mirc.com here
although obviously this list does not include every server in existance ...
perhaps your city has a webpage .. and perhaps if they do have an irc server the information is on it? ... beyond that i'm not sure what to tell ya.
