You can quickly verify  your CNAME record using a web based dig tool:

  1. Visit http://www.mxtoolbox.com/CNAMELookup.aspx
  2. Enter your custom domain's URL in the 'Domain Name' field
  3. Click CNAME Lookup

The results show you:

    • Type - the type of record created for your subdomain
      • If your DNS settings are correct, you will see 'CNAME' in this field
      • If you do not see 'CNAME' in the response and only see 'A' then there may be an A Record in your DNS that is overriding your CNAME Record.  This A Record will need to be deleted or changed because you cannot have an A Record and a CNAME record created for the same subdomain.
    • Domain Name - the domain you searched
    • Canonical Name - the host your domain points to
      • If your DNS settings are correct, you will see "unbouncepages.com" in this field
      • If you see a different value, you will have to edit the host (or points to) value of this subdomain in your DNS settings to be "unbouncepages.com"
      • Note: you might see something like "unbouncepages.com.yourdomain.com" in this field. If you do, you'll have to return to your host and edit the points to value of your CNAME record to be "unbouncepages.com." (note the extra . at the end)
    • TTL - your time to live value
      • This is the amount of time your server holds on to older cached information before it refreshes to show any new changes.  If your custom domain does not seem to be working properly, you may just need to wait the amount of time indicated before your custom domain will work.

For example:

If you look up the domain "www.cheapelephants.com" you will see the following result:


This shows that the domain "www.cheapelephants.com" is correctly pointing to "unbouncepages.com" with a CNAME record.

This is the kind of result you're after.
