I am working form an internal network perspective. I am trying to point rosy.example.com to Example Web Page which resolves to (dummy IP) using CNAME for rosy.example.com. I am running a drupal multisite in which I am hosting 12 subdomain names on one IP . The issue is that the CNAME is not resolving.

CNAME Settings in IManager

domain: example.com
owner name: rosy
record type: CNAME
Resource Record Data

Enter Domain Name of Host Aliases:
Example Web Page

then I load and unload named

nothing. can anyone help?
