DNS Lookup Tool
Check DNS records for any domain. View A, AAAA, MX, NS, TXT, CNAME, SOA, and CAA records. Enter an IP address for reverse DNS lookup.
DNS Record Types Explained
A & AAAA Records
Maps domain names to IPv4 (A) and IPv6 (AAAA) addresses
MX Records
Specifies mail servers responsible for receiving email
NS Records
Lists authoritative name servers for the domain
TXT Records
Contains text data including SPF, DKIM, and verification records
Understanding DNS Records
DNS (Domain Name System) is the internet's phone book, translating human-readable domain names into IP addresses that computers use to communicate. Different DNS record types serve different purposes in this translation process.
Common DNS Record Types:
- A Record – Maps a domain to an IPv4 address (e.g., 93.184.216.34)
- AAAA Record – Maps a domain to an IPv6 address
- MX Record – Specifies mail servers for the domain with priority values
- CNAME Record – Creates an alias pointing to another domain name
- TXT Record – Stores text data, commonly used for SPF, DKIM, and domain verification
- CAA Record – Specifies which Certificate Authorities can issue SSL certificates
Reverse DNS Lookup
Enter an IP address instead of a domain to perform a reverse DNS (PTR) lookup. This shows you which domain names are associated with a specific IP address, useful for verifying email server configurations and investigating network issues.
