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)
Certification Authority Authorization (CAA) 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
