naked domain

From IndieWeb


A naked domain (also known as a root domain or zone apex) is a domain name (like indieweb.org) that doesn’t start with β€œwww.” or any other subdomain and is preferred for IndieWeb sites as identifying yourself starting with W-W-W gets tiresome quickly. Sites that use naked domains can offer naked URLs which are shorter than those prefixed with β€œwww.” and thus better URL design.

Apex technical details

The zone apex is the part of DNS that contains an the SOA and NS records for a DNS zone. If you have a site www.example.com, then then the apex is example.com. The www. portion might be a dedicated host (or load balancer) for serving Web traffic (as opposed to other Internet services. The DNS specification forbids serving a naked domain with a CNAME at the apex. Some DNS providers, such as CloudFlare, give the appearance of support for CNAME at the apex by simulating it by "CNAME flattening", which accepts a CNAME in the configuration panel as if it were allowed, but silently serves up an A record with the correct IP for DNS queries. Some providers might also call this an ALIAS record, which is not a real DNS record, but the name for the placeholder which uses the same strategy.
