Hi Wilkes,

Could you connect via ssh to your BIG IP and try following commands :

nslookup hostname.domain.com

If it resolves the incorrect IP:

1) verify that you don't have this entry in the BIG IP host file From the GUI go to: System ›› Configuration : Device : Hosts

2) verify that the DNS servers are updated (if you have multiple DNS server maybe they are not in sync)

From the GUI go to : System ›› Configuration : Device : DNS

3) flush DNS cache on the BIG IP and try again
