Website domain does not resolve to new domain via internal network...only externally.

We are having an issue with resolving a website address internally.

Our original company website www.123.com, was redesigned and is now named www.1234.com.  Typing in www.123.com will resolve to www.1234.com.

However, if you are connected to internal internet and enter www.123.com, you resolve to www.123.com and you do not get forwarded to www.1234.com

This only happens with desktops/laptops, phones resolve properly.  Have tried with systems that were not part of local domain, issue is the same as long as connected to internal internet connection.  The website was never hosted internally.

We've looked through our Sonicwall tz400 and can't find anything.  Nothing on Barracuda web filter either (wasn't likely, but had to look).

Where could a rule/setting to cause this exist?

Probably there is a DNS entry set manually on your local DNS server for www.123.com. Did the IP address change too?
You can try if DNS resolution is the issue by looking at the results of:
nslookup www.123.com
nslookup www.1234.com
nslookup www.123.com 8.8.8.8
nslookup www.1234.com 8.8.8.8

Open in new window

The latter two lookups force to use a public Google DNS server.

We aren't 100% sure on this just yet, but there WAS an entry in the forward lookup pointing to the ip for www.123.com, we changed it to the current one and will see where we end up once things propogate.

TY!
