Domain Name System (DNS)

• An Internet service that translates domain names into IP addresses.

• Computer sends request to the nearest DNS server which returns the IP corresponding to the domain name.

Domain Record

• NAME is the fully qualified domain name of the node in the tree.

• TYPE is the record type. It indicates the format of the data and it gives a hint of its intended use. For example, the A record is used to translate from a domain name to an IPv4 address, the NS record lists which name servers can answer lookups on a DNS zone, and the MX record specifies the mail server used to handle mail for a domain specified in an e-mail address

DNS record types

• A – Maps to IPv4
