This kind of domain names are considered premium domains and are sold are a higher amount than other domain names.
Types Of Reserved Domains.
There are basically four types of reserved domains which will be list below.
Example Reserved Domains.
Example Reserved Domains is reserved by the Internet Engineering Task Force (IETF) as a special domain name that will not be made open as a global domain and will not be installed as a top-level-domain in the world of the internet Domain Name System (DNS).
When domain names are presented as references of the use or introduction of definitions of the Domain Name System or the Internet, the top-level domain example is specifically meant to be used in documents or other technical writing.
Invalid Reserved Domains.
Invalid Reserved Domains are often used in Uniform Resource Identifiers (URIs) as a pseudo domain name to process an error state or for privacy protection.
The domain name anonymous. invalid in a SIP URI means hiding a caller’s identity and is a noteworthy example of this use in the Session Initiation Protocol (SIP).
Localhost Reserved Domains.
In most TCP/IP networks, the loopback protocol is known as localhost, and it resolves to the IP addresses 127.0.0.1 in IPv4 and::1 in IPv6. The name has been specified statically in host DNS implementations as a top-level domain, with address records (A and AAAA) pointing to the same loopback addresses. Every such use is incompatible with commonly used algorithms.
