If I have an address record setup as follows...

www.mywebsite.com  111.1.1.1
*.mywebsite.com    111.1.1.2

and a CNAME setup as follows...

beta.mywebsite.com 111.1.1.3

Would pinging beta.mywebsite.com resolve to 111.1.1.2 or 111.1.1.3? How long does it take to refresh after changing.

The very same server has multiple interfaces on different subnets. Let's… >>> More
