The types of information elements are categorized and organized with a list of DNS record types, the resource records (RRs). Each record has a type (name and number), an expiration time ( time to live ), a class, and type-specific data.
MX record. A mail exchanger record ( MX record) specifies the mail server responsible for accepting email messages on behalf of a domain name. It is a resource record in the Domain Name System (DNS).

Split-horizon DNS. In computer networking, split-horizon DNS (also known as split-view DNS, split-brain DNS, or split DNS) is the facility of a Domain Name System (DNS) implementation to provide different sets of DNS information, usually selected by the source address of the DNS request. This facility can provide a mechanism for security and ...
A Canonical Name ( CNAME) record is a type of resource record in the Domain Name System (DNS) that maps one domain name (an alias) to another (the canonical name). [1] This can prove convenient when running multiple services (like an FTP server and a web server, each running on different ports) from a single IP address.
Contains a link to the next record name in the zone and lists the record types that exist for the record's name. DNS resolvers use NSEC records to verify the non-existence of a record name and type as part of DNSSEC validation.
nslookup (from name server lookup) is a network administration command-line tool for querying the Domain Name System (DNS) to obtain the mapping between domain name and IP address, or other DNS records .
