redirecting users

[o_O]

Is there any way to redirect users from one irc server to another and that another server would be hiden.
Example: users are connecting to irc.whatever.com and that server would redirect them to irc1.whatever.com and irc1.whatever.com wouldn't have dns record. That way if someone start DDoS attack he could attack only irc.whatever.com, users would be on irc1.whatever.com.
I know how to protect HUB and services from DDoS but thing is when someone attack irc server all users just go because net split etc.
Is it possible to do something like this if so can someone help.

not really, all a user has to do is monitor packets and get the IP of the hidden server. Plus if irc,* is attacked then it's likely new users will fail to connect thus killing the forward.

Unfortunately, if the server is publicly available, it can be attacked. DDoS mitigation is the best defense in this case.
