DNS Domain Resolver
Look up all DNS records for a domain — A, AAAA, CNAME, MX, TXT, NS, SOA and SRV.
DNS record types explained
A record (Address)
Maps a domain to an IPv4 address — the most common record type, e.g. example.com → 1.1.1.1.
AAAA record (IPv6 Address)
Maps a domain to an IPv6 address, e.g. example.com → 2001:db8::1.
CNAME record (Canonical Name)
An alias that points one domain to another, e.g. www → example.com.
MX record (Mail Exchange)
Mail exchange records point to the servers that handle email for the domain, with a priority and server address.
TXT record (Text)
Text records are commonly used for SPF anti-spam validation and domain ownership verification.
NS record (Name Server)
Name server records specify the DNS servers authoritative for the domain.
SOA record (Start of Authority)
The Start of Authority record holds administrative info such as the serial number and refresh intervals for the zone.
SRV record (Service Record)
Service records define the host and port for specific services such as SIP or XMPP.
Common use cases
Site migration, load-balancing setup, CDN configuration, business email setup, SSL certificate validation and domain-ownership verification.
