You could, sure.  That's fine for testing purposes, but most people
don't know their own IP addresses.  Many people don't have a DNS entry
for their home PC.  Also, what about NAT?

Again, not every computer has a DNS address.  If you are going to ask
a user to hand enter their IP address, it would make sense to accept
either a numeric IP address, or a DNS name.

Sure, but now you have to write (or embed) an IRC client.  Do you need
to worry about someone joining your channel that isn't using your game
client?  Does that have potential security implications?

That depends on the delay from each client to the IRC server.

You're going to have to learn quite a bit about networking and
probably client / server architecture to write a networked game.
