Com

com is a top-level domain in the Domain Name System (DNS) of the Internet. It is one of the original generic top-level domains (gTLDs) introduced in 1985, alongside other early TLDs such as .org, .net, and .edu. The .com domain was originally intended for commercial entities but quickly became the default choice for a wide range of websites, and it is now the most widely used TLD worldwide.

Administration and registration: The registry for .com is operated by Verisign under a contract with ICANN. Registrations are processed through ICANN-accredited registrars. Registrants range from individuals to corporations, and information about domain ownership is maintained in the WHOIS database, subject to privacy rules and regulatory requirements.

Naming and policies: A .com label must be 3 to 63 characters in length and can include letters, digits, and hyphens, but cannot start or end with a hyphen. Domain names are generally case-insensitive. Internationalized domain names can be registered in punycode for non-ASCII characters, with the DNS storing ASCII representations for .com.

Current status and use: .com is the most popular TLD by number of registered domains, occupying a large share of the global domain market. It is widely used for commercial sites, brand portfolios, blogs, and personal pages. As of 2023, there were over 150 million registered .com domains, underscoring its central role in the structure of the modern Internet.
