What is a CNAME Record?

A CNAME record (canonical or alias) maps a hostname to a hostname, e.g. (store.massivedns.com -> massivedns.com)

In the above example, anyone visiting ‘store.massivedns.com’ will be pointed to the root domain, ‘massivedns.com’.

This behaviour indicates that ‘store.massivedns.com’ is an alias of ‘massivedns.com’ (canonical).

Unlike A records or AAAA records, CNAME records only map to human readable addresses (not IP addresses)
