ehh... just point irc.domain.com to the ip of your first server..
then add another irc.domain.com record and point that to the ip of your second server... now if a user connects to irc.domain.com, they will get sent to a random one of your servers

even if i add random IPs for example im on the server and one of them got d/c shouldnt user automaticly set to other server without user getting d/c and re-connecting ...just auto switch users to the server that is "Online" so ur saying just adding "Random IP" it will allow them to swtich without any re-connecting, i don't wanna users to get disconnect, i want them to stay logged in and just switch them into the *server* which isn't down, without them re-connecting

It seems that you're looking for an IRC "cluster" which, please feel free to correct me if I'm wrong, is not supported in unreal yet, is it? .

That's simply not possible. Let me explain it this way. You and your neighbor have a private telephone line to eachother. There is a wire that runs directly from your house into his. Tomorrow, your neighbor is moving down the block. Will your private phone line automatically work at his new house? No. Someone needs to run a new wire into his new house in order for it to work.

That's the same thing with an Internet connect. When you connect to a server, you create a socket. The socket links you to that server. If the socket breaks (e.g., the server goes down) then the connection is lost. You can't just magically have it connect you to another server, you have to initiate a completely new connection. In fact, what you want would be VERY dangerous. Imagine the scenario where I "trick" the server into redirecting you. Rather than going to irc2.thenetwork.com you go to irc2.mynetwork.com which then records and steals your passwords. Or consider for web surfing. Just as you're about to complete your Amazon.com order, I trick it into redirecting you to my website where I log your credit card information.

The only way to create a new connection to a server when another server dies is for the client to initiate the connection. There is (thankfully) no way around that. It's not a limitation of Unreal, it's just how sockets work.
