Our design company has moved our website to another IP. Fine, not a problem. We updated the IP within our domain portal to point to the new IP. The website works fine externally to our network.
The problem is local on our LAN. We have split DNS and sop changed the IP address of the www record in DNS. However its not loading the website.
If i do a nslookup on the www. address its showing the old IP and non-authoritative answer. The internal split DNS domain is showing the correct IP.
