Hosting DNS Dot Termination

When creating a DNS Resource Record (RR) of type NS, MX, CNAME or SRV, the Hostname specified in the last column (Host name) should be terminated with a “.” if the hostname is external to your zone. Otherwise, the domain name for which the zone belongs will get appended at the end of the hostname.

In this example, two CNAME records are being created.

• ftps.privacyadvocate.org is being pointed to ftp.R4L.com.
• login.privacyadvocate.org is being pointed to login.R4L.com.

The name of the domain is appended to both ftps and login, as these are not dot terminated. Both ftp.R4L.com and login.R4L.com are dot terminated, so these do not get the domain name appended.
