About DNS Lookup
The DNS Lookup tool lets you query DNS records for any domain name. DNS (Domain Name System) is the internet's phone book — it translates human-readable domain names into IP addresses and other records that computers use to communicate. This tool queries public DNS servers to retrieve A, AAAA, CNAME, MX, TXT, NS, and SOA records, helping you troubleshoot DNS issues, verify configurations, or research domain infrastructure.
Frequently Asked Questions
What are DNS records?
DNS records are entries in the Domain Name System that map domain names to various types of data. They are the backbone of the internet's naming system, translating human-readable domains like example.com into IP addresses and other information that computers use to route traffic.
What is an A record?
An A record maps a domain name to an IPv4 address. It's the most fundamental DNS record type and is what allows browsers to find the server hosting a website.
What is an MX record?
MX (Mail Exchange) records specify the mail servers responsible for receiving email for a domain, along with priority values. Lower priority numbers indicate higher preference.
What is a TXT record?
TXT records store arbitrary text data associated with a domain. They're commonly used for email authentication (SPF, DKIM, DMARC), domain verification, and other purposes.
Which DNS server does this tool query?
This tool queries Google's public DNS servers (8.8.8.8) via their DNS-over-HTTPS API, providing fast and reliable results from one of the world's largest DNS resolvers.
