What is the highest domain?
In the domain name (DNS) system, which is used to allow people to write words rather than numerical web addresses to achieve a particular website, the highest domain is the last part of the domain name after the final aunt. For example, in Wisegeek there is a domain of the highest level "com". The highest level domains fall into a number of different categories, depending on who can use them. Within this system, which is administered by the Internet Corporation for the assigned names and numbers (ICANN), users can write in words or range of characters that are easier to remember than numbers strings. Each domain includes the highest level, the second level and the third level or the subdomain. Instead of telling people interest in Volkswagonna, for example, the company could tell customers to go to Volkswagon.com. The DNS system is sometimes compared with a phone book because it allows people to find a person, product or service by name to remember the right number.
Web address, such as www.wisegeek.com, is considered the name of the domain. The first part of the address, "www" is the third level or subdomain. "Wisege" is the second level and "com" is the domain of the highest level. Individual domain owners can create more subdomain in the second level domain, such as the "example" subdomain in example.Wisegeek.com. Many people refer to second -level domains as "domain names" because people often refer to the pages only by the second -level domain. However, several websites can have the same second level and different top -level domains, which is important to announce a domain in full to prevent confusion.
The highest levels such as "com", "org" and "net" are general. Anyone can register domain names in one of these domains at the highest level. Some other general domain options of the highest level such as "Edu", "Gov" and "Mil" are limited to people who can prove that MAShe eats a legitimate reason to use them. There are also top -level domains sorted by country, such as "IE" for Ireland, as well as sponsored domains controlled by various industries.
If someone wants to register a new domain name, they have the highest level to choose from, provided that these domain names are no longer taken and that they are entitled to use a specific domain. Some people like to be creative with the domain names at the highest level, as in the case of the Social Bay page Delicious, which registered the domain of ICIO.US to create a subdomain "del" and spell del.icio.us with his domain name.
