Mobile redirect to subdomain

What do you type into your browser on the browsers which don't work? Do you type m.woodlandbeachresort.com? And what do you get? Does it redirect to either www.woodlandbeachresort.com or woodlandbeachresort.com?

Hello,

For me it says:

Code:
m.woodlandbeachresort.com: Non-existent domain
 
What do you type into your browser on the browsers which don't work? Do you type m.woodlandbeachresort.com? And what do you get? Does it redirect to either www.woodlandbeachresort.com or woodlandbeachresort.com?

Jeff

If you try www.woodlandbeachresort.com or woodlandbeachresort.com on a smartphone it will redirect to m.woodlandbeachresort.com.

If I type m.woodlandbeachresort.com on my smartphone or browser I get "Server not found."
 
I think I found the problem:
Code:
[jeff@office ~]$ dig m.woodlandbeachresort.com

Once again showing that dig is a much better diagnostic tool than is nslookup.

While NXDOMAIN is technically correct, by showing the IP# dig shows the problem.

CNAME records must never point to an IP#. They must point to a name, not an IP#.

Possibly some programs work because they ignore the difference, but if you want it to work you must do it according to the RFCs :).
