DNS Record Lookup

Look up A, AAAA, CNAME, MX, TXT, NS, and other DNS records for any domain.

Enter a domain name and select a record type to look up DNS records.

What Is a DNS Lookup?

A DNS lookup (or DNS resolution) is the process of converting a human-readable domain name like example.com into a machine-readable IP address. When you type a website URL into your browser, a DNS lookup happens behind the scenes to find the server that hosts the website.

This tool lets you directly query DNS records for any domain, showing you the raw DNS data that powers the internet's naming system.

Common DNS Record Types

A (Address) — Maps a domain to an IPv4 address. The most common record type, used to point a domain to a web server.
AAAA — Maps a domain to an IPv6 address, the newer IP address format.
CNAME (Canonical Name) — Maps a domain to another domain name. Used for subdomains and aliases.
MX (Mail Exchange) — Specifies the mail servers responsible for receiving email for a domain.
TXT (Text) — Stores text information, commonly used for email security (SPF, DKIM, DMARC) and domain verification.
NS (Name Server) — Indicates which DNS servers are authoritative for a domain.
SOA (Start of Authority) — Contains administrative information about a domain, including the primary name server and zone refresh intervals.
SRV (Service) — Specifies the location of specific services like SIP or LDAP.

How to Use the DNS Lookup Tool

Enter a domain — Type the domain you want to look up (e.g., example.com). Do not include http:// or www.
Select record type — Choose the DNS record type you want to query. A is the most common.
View results — The tool will display the record name, type, TTL (time to live), and value.

How DNS Lookup Works Under the Hood

This tool uses Cloudflare's DNS-over-HTTPS API (cloudflare-dns.com/dns-query) to perform DNS lookups directly from your browser. DNS-over-HTTPS encrypts DNS queries using HTTPS, preventing eavesdropping and manipulation of DNS data between your browser and the DNS resolver. This is more private and secure than traditional unencrypted DNS queries.
