Create CNAME Without Owning the Target Domain

Manage domain names for a server in the server farm.

This article applies to: Managed Servers


If you are pointing an Internet hostname that belongs to your Internet domain at a webserver provided by the IT datacenter or by a non-Cornell web hosting company, you can do so by creating a CNAME DNS record.  

If you'd like the Systems Support group to do this for you, send email to systems-support@cornell.edu.

Example

  • Your domain: example.com
  • Your webserver: sf-abc.serverfarm.cornell.edu
  • DNS CNAME record: www.example.com.  CNAME sf-abc.serverfarm.cornell.edu.
  • Name: www.example.com

If your domain is enrolled in Cornell's DNSDB with you as netadmin, you can create a CNAME using the DNSDB batch facility. 

  1. Connect to: http://dnsdb.cit.cornell.edu/dnsdb-cgi/batch.pl.
  2. Enter your batch command(s) in the text area. For example:
    addcname myfiles.cals.cornell.edu sf-abc.serverfarm.cornell.edu
    addcname myotherfiles.cals.cornell.edu cloudhost001.provider.com
  3. Select Allow cnames to point to a target domain you do not own.
