Fundamental

  • CNAME: is a Canonical Name Record or Alias Record. A type of resource record in the Domain Name System (DNS), that specifies that one domain name is an alias of another canonical domain name.

  • A and AAAA Record: An A and AAAA record are actually primary DNS records. They associate a domain name with a specific IP address.

  • TXT Record : A TXT record (short for text record) is a type of resource record in the Domain Name System (DNS) used to provide the ability to associate arbitrary text with a host or other name, such as human readable information about a server, network, data center, or other accounting information.

  • MX(Mail Exchanger) 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). It is possible to configure several MX records, typically pointing to an array of mail servers for load balancing and redundancy.

  • NameServer: Nameserver is a server on the internet specialized in handling queries regarding the location of a domain name's various services. Nameservers are a fundamental part of the Domain Name System (DNS). They allow using domains instead of IP addresses.
