Multiple IP addresses for one A Record in DNS

[ryoun1b]

Hi There,

I am trying to figure out how to add one A record that will return 5 IP addresses. Is there any way to do this with ONE A RECORD?

The point here is that I am trying to create a VPN tunnel using a FQDN that will resolve to one of a pool of 5 IP addresses.

Anyone have any ideas how I can set this up in my DNS?

Thanks!

No I don't think this is possible. A records are 1 to 1. Map a hostname to an IP address.

If you want one IP to resolve to multiple IP addresses, you would have to use some kind of load balancing.

For example, in Windows 2000/2003 you can create Network Load Balancing clusters. User access the cluster using one Virtual IP address or Hostname. This one address is then routed to two or more server IP addresses.

RoundRobin
A Roundrobin is a local balancing mechanism used by DNS servers to share and distribute network resource loads. You can use it to rotate all resource record (RR) types contained in a query answer if multiple RRs are found.

There are several sites that explain how to set this up, it might help with that you are looking for.

Theres a pretty extensive article on the MS DNS Help as well as for Bind.
