The Domain Name System. Name server; Domain names. The DNS is able to store many types of information, even the mail server lists for a specific domain.

The TTL is set by the administrator of the authoritative DNS server. The period of validity may vary from a few seconds to days or even weeks. Results obtained from a DNS request are always associated with the time to live (TTL), an expiration time after which the results must be discarded or refreshed. A standard practice in implementing name resolution in applications is to reduce the load on the Domain Name System servers by caching results locally, or in intermediate resolver hosts.

A common method is to place the IP address of the subject host into the sub-domain of a higher level domain name, and to resolve that name to a record that indicates a positive or a negative indication. The DNS is used for efficient storage and distribution of IP addresses of blacklisted email hosts.

Com into a web browser, a server behind the scenes will map that name to the IP address 206. The domain name system (DNS) is the way that internet domain names are located and translated into internet protocol (IP) addresses.

An often-used analogy to explain the Domain Name System is that it serves as the phone book for the Internet by translating human-friendly computer hostnames into IP addresses. Com translates to the addresses 93. For example, the domain name www. 119 (IPv4) and 2606:2800:220:6d:26bf:1447:1097:aa7 (IPv6). Unlike a phone book, DNS can be quickly updated, allowing a service’s location on the network to change without affecting the end users, who continue to use the same host name. Users take advantage of this when they use meaningful Uniform Resource Locators (URLs), and e-mail addresses without having to know how the computer actually locates the services.

Types of DNS Domain Names. Of each name type. The name of hosts operating DNS servers specified in the name_server.
