Check if you can ping website domain name and it shows correct IP, then it should work with domain name on 10.1.20.x as well. but if it is not able to ping then check NIC IP address setting on 10.1.1.x if it is having any DNS name, same DNS name should be entered in 10.1.20.x NIC IP Address settings.

Or you can create a Host file entry with IP and Name

Path of host file entry is C:\Windows\System32\drivers\etc\Hosts.

Edit hosts file and put below line.

10.1.1.x site's domain name.
