What Is a CNAME Record

A CNAME Record (Canonical Name Record) is a type of DNS Record that shows one domain as an alias for another domain — the so-called canonical domain. This is efficient when you run multiple services, with different ports, but from a single IP Address.

CNAME Records must always point to another domain name, never directly to an IP Address.

You should avoid pointing one domain with a CNAME Record to another domain name with a separate CNAME Record, as this is inefficient. Instead, you should point both domains to the same A Record.

Uses of CNAME Records are often maximised by business owners and companies by pointing several websites owned by the same organisation to a primary website.
