DNS Lookup
Query all DNS records of any domain – nameservers, A, AAAA, MX, TXT, CNAME and SOA records at a glance.
How DNS Lookup Works
The Domain Name System (DNS) is the phone book of the internet. Every domain has DNS records that define where requests are routed. NS records show the nameservers, A records the IPv4 address, MX records the mail server, and TXT records can contain SPF, DKIM and other verification data.

Frequently Asked Questions about DNS Lookup
What are DNS records and what are they used for?
DNS records (Domain Name System entries) are database entries that assign various information to a domain. A records point to IPv4 addresses, AAAA records to IPv6 addresses, MX records to mail servers, NS records to nameservers, and TXT records contain freely definable text (e.g. for SPF or DKIM email authentication).
What is a nameserver (NS record)?
Nameservers are the authoritative servers for a domain. They know which IP address belongs to which domain. When you register a domain, you set the nameservers at your registrar. These point to the DNS server of your hosting provider, which then manages all further records.
What does TTL mean in DNS records?
TTL (Time To Live) specifies in seconds how long a DNS record may be cached by other servers. A TTL of 3600 means the record can be cached for up to 1 hour. Low TTL values are useful when you want DNS changes to propagate quickly – but increase the load on nameservers.
