Record Types

NS1’s cutting edge DNS platform supports most common DNS record types — and some fancier ones too.


A DNS record is the basic unit of information in the DNS. A record is identified by a domain name (like www.example.com), a type (like A, AAAA, MX, NS, and so on) indicating the type of information contained in the record, some control information like DNS cache time-to-live (TTL), and "answer" data like server IPs, mail hosts, etc, depending on the record type. NS1 supports the following DNS record types:

A Address (IPv4) AAAA Address (IPv6)
AFSDB AFS database ALIAS Zone apex alias (NS1 specific)
CERT (certificate) CNAME Canonical name
HINFO Host info MX Mail exchange
NAPTR Naming authority pointer NS Nameserver
PTR Pointer (reverse) RP Responsible person
SPF Sender policy framework SRV Service locator
TXT Text
