Point Multiple IP Addresses to a Single Host Name

I want a host name such as "www.dacracot.org", to point to multiple IP addresses, "1.2.3.4" and "1.2.3.5".

Is this set up by my DNS people? What is the correct terminology?

I call BS, that is in no way the same question. – dacracot Apr 05 '11 at 20:08 — dacracot, Apr 05 '11 at 20:08

It is called Round robin DNS; Yes it is set up at the DNS level. All you have to do is add mutiple A records to your Nameserver. Be fore warned, It is not the best load balancing/redundant solution. Have a look at Even's post here for more info Uneven round-robin DNS (i.e. not round-robin)?

So I have redundant load balancing set up behind the two addresses I want pointed to as the same host. Will clients switch to 1.2.3.5 if 1.2.3.4 goes down? – dacracot Apr 05 '11 at 20:01
