A domain name is a string that identifies a realm of administrative autonomy, authority or control within the Internet. Domain names are used in various networking contexts and for application-specific naming and addressing purposes.
On March 15, 1985, Symbolics.com became the first officially registered .COM domain. Symbolics Computer Corporation originally purchased the domain for their pioneering computer development company. The domain name has since been acquired and sells advertising on the homepage.
Different domain extensions have different rules and regulations, but many domain name facts hold true in a general sense. For example, most TLDs require your domain name to be no longer than 63 characters. It’s the standard for the most popular TLDs and many country code domains as well.
