DNS Server returning wrong info?

I have set up a new RDS farm consisting of 2 servers 'RDS1' and 'RDS2', with a separate machine doing the session broker role 'RDSSB'.

They're all set up properly, with RDSSB having been entered on each as the Session Broker. They each have their own DNS A records, consisting of a single IP address per server. I then have 2 more DNS A records which have the same name 'RDSFarm' with the 2 IPs for RDS1 and RDS2.

However, when I nslookup, I'm getting a third IP for a completely different device (our SAN device!).

There is no record for it in our DNS. None whatsoever.

So why am I getting a third IP?

Ignore that. Even though the server responding was returning the record and it wasn't there, after 5 minutes of refreshing, it suddenly appeared!

Deleted now.
