Google sent out an email to Admins stating that they were no longer supporting YouTube for Schools. Instead, they say, if we want restricted content we should:

Configure Domain Name System (DNS) on your network so that restrict.youtube.com is a Canonical Name (CNAME) for the following hostnames:

  • www.youtube.com
  • m.youtube.com
  • youtubei.googleapis.com

I'm using Microsoft DNS and I can create the domains youtube.com and googleapis.com with no problem. The problem that I am running into is creating two restrict.youtube.com CNAMEs for www.youtube.com and m.youtube.com. My research indicates that this is a violation of the RFC's and Microsoft DNS will not allow it. Any idea how to perform what Google requires? I can't create A recs for www.youtube.com and m.youtube.com and point them to restrict.youtube.com because they require an IP.

Thanks in advance.

Not familiar with MS DNS, but it seems that you should do the opposite of what you are doing. I mean, you are probably doing:

restrict.youtube.com. CNAME www.youtube.com.
restrict.youtube.com. CNAME m.youtube.com.

Which means that "restrict.youtube.com have the same IP address as www.youtube.com AND m.youtube.com". Probably you want the opposite:

www.youtube.com. CNAME restrict.youtube.com.
m.youtube.com. CNAME restrict.youtube.com.

which means "www.youtube.com and m.youtube.com will use the same IP address as restrict.youtube.com"

To add an alias (CNAME) resource record to a zone using the Windows interface Open DNS Manager.

  • In the console tree, right-click the applicable forward lookup zone, and then click New Alias.

  • In Alias name, type the alias name.

  • In Fully qualified domain name (FQDN) for target host, type the FQDN of the DNS host computer for which this alias is to be used.

  • As an option, you can click Browse to search the DNS namespace for hosts in this domain that have host (A) resource records already defined.

  • Click OK to add the new record to the zone.

Or if you want to edit the zone file: 

www.youtube.com CNAME restrict.youtube.com. // For Desktop Version of Youtube

m.youtube.com CNAME restrict.youtube.com.  // For Mobile Version of Youtube
