  3. Basic DNS Record Types

Name Description
A - Address Record 32 bit IPV4 - maps hostnames to ip addresses
A + Dynamic DNS Record Method of automatically updating a name server in the Domain Name System (DNS), often in real time, with the active DDNS configuration of its configured hostnames, addresses or other information
AAAA - Quad A Record 128 bit IPV6 - maps hostnames to ip addresses
CNAME - Canoncial Name Alias of one hostname to another
NS - Name Server Delegates a DNS zone to use the given authoritative name servers
SRV - Service Locator Generalized service location record, used for newer protocols instead of creating protocol-specific records such as MX.
TXT - Text record Originally for arbitrary human-readable text in a DNS record. Since the early 1990s, however, this record more often carries machine-readable data, such as specified by RFC 1464, opportunistic encryption, Sender Policy Framework, DKIM, DMARC, DNS-SD, etc.
URL Redirect Record Can be used for publishing mappings from hostnames to URIs.
