DNS - Alias record

1 - About

An alias is a DNS record with a name that resolves directly to an ip_address.

A cname has also an alias functionality but as it resolves a name to another name and not to an ip address, the DNS resolver needs therefore another roundtrip to get the final ip_address. The CNAME record is then slower than an ALIAS record.

2 - Management

2.1 - Creation

Before creating an ALIAS record, check there are no:

  • URL Redirect (Unmasked/Masked/Permanent),
  • A or AAAA records

set for the same Host (e.g., yourdomain.tld or example.yourdomain.tld) because they can conflict with each other.
