Difference between SYNONYM and ALIAS

A synonym domain name and an alias domain name can both serve as secondary domain names to another domain name.

For example, the domain names apple.fr (alias) and banana.fr (synonym) can redirect to the domain name fruits.fr (the primary domain name).

The difference between a synonym and an alias is technical:

• A synonym domain name is based on the DNS of the primary domain name
• An alias domain name has its own DNS
