Frequently Asked Questions
ā What is a CNAME record?
A CNAME (Canonical Name) record maps one domain name to another, creating an alias. Example: www.example.com ā example.com.
ā Can I use CNAME for root domains?
Standard DNS doesn't allow CNAME at the zone apex (root domain). Some providers offer ALIAS/ANAME records as alternatives.
ā What's the difference between CNAME and A records?
A records point to IP addresses directly. CNAME records point to another domain name, which then resolves to an IP.
