One DNS multiple servers

[w1nn3r]

Heres the problem. I have a single DNS i want to route traffic to, But i have 3 servers(On 3 different ISP's) that i want to distribute that traffic to. We all run linked chat servers, And want everyone to join through irc.mydomain.com. But i can only point that to a single IP address. Another problem we have is, That one of the servers that is linked is the server that irc.mydomain.com is pointing to. So i have all the servers listening on higher ports, But that still doesnt help me with my load balancing issue. I can alias out different names (chat.mydomain.com, irc.mydomain.com, ircd.mydomain.com) But we want all clients to join through a single point.

Hi,

Did you try to add 'A' or 'CNAME' records with the @IP of each of your servers - Let suppose the names of your servers are srv1, srv2 and srv3.
Let suppose thier @ip are :
srv1 - 192.x.x.1
srv2 - 192.x.x.2
srv3 - 192.x.x.3

Add 3 host records 'A' to your DNS Domain :
srv1.mydomain.com 192.x.x.1
srv2.mydomain.com 192.x.x.2
srv3.mydomain.com 192.x.x.3

Then add 3 CNAME records pointing to your 3 servers :
irc.mydomain.com => srv1.mydomain.com
irc.mydomain.com => srv2.mydomain.com
irc.mydomain.com => srv3.mydomain.com

Then let Round Robin work for you. If your DNS is round robin compatible then each request will send a different @IP for irc.mydomain.com

Didn't test it, hope it will works
