Domain Names Directory

The term may refer to any type of domain within the computer field, since there are several types of domains. However, today, it often refers to the address of an Internet site. The term domain name has multiple meanings, all related to the Domain Name System. It is a name that is entered into a computer (e.g. as part of a Web site or other URL, or an e-mail address) and then looked up in the global Domain Name System which informs the computer of the IP address with that name. it is the product that registrars provide to their customers. It is a name looked up in the DNS for other purposes.

Domain names are hostnames that provide rememberable names to stand in for numeric IP addresses. They allow for any service to move to a different location in the topology of the Internet (or another internet), which would then have a different IP address.

Every domain name ends in a top-level domain (TLD) name, which is always either one of a small list of generic names (three or more characters), or a two characters territory code based on ISO-3166 (there are few exceptions and new codes are integrated case by case).
