For this use case you want to run IRC over SCTP, so that you can keep
the connection open when you change IP addresses. The best that can be
done with TCP is to automatically reconnect from the new IP address
when the old TCP connection breaks.

Using SCTP requires of course that the IRC server listens for SCTP
connections. There must also not be any overzealous firewalls that
block SCTP just because they don't know what it is.
