Hacker News article Domain expansion is when the domain name (DNS) is changed, usually in order to expand a domain or subdomain (the “global” part of a domain name).
The domain expansion is a legal extension of the DNS, and it allows the domain holder to add more domain names in the same area.
For example, a domain that previously held the name “david” could now be registered as “davidsdavid.com”.
Domains that are registered in the United States are typically assigned numbers, and these are usually referred to as domain names.
A domain name is a series of letters and numbers.
Domain expansion allows a domain holder or registrar to register the domain or a subdomain, which can be any part of the Internet.
Domain name extensions (DNOs) are used by other organizations to include more domains in their DNS names.
For instance, a website like Twitter can register a website in a DNS name like “twitter.com”, but the company also has a “www.twitter.net” website in its DNS name.
Domain names are also used by online retailers, which are able to include a “store.com” domain name, but only one “www1.store.co.uk” domain in their domain names, for example.
Domain extensions are allowed in domains.
When domain expansion occurs, the name of the domain that is expanded will be used.
