DNS Lookup
Query DNS records for any domain name. Check A, AAAA, MX, NS, TXT, and CNAME records.
What Are DNS Records?
DNS records are like the entries in a phone book for the internet. They map domain names to various types of information, including IP addresses, mail servers, and text-based verification data. There are several types of DNS records, each serving a different purpose:
- A Record — Maps a domain to an IPv4 address
- AAAA Record — Maps a domain to an IPv6 address
- MX Record — Identifies mail servers for the domain
- NS Record — Identifies authoritative name servers for the domain
- TXT Record — Contains text information (often used for verification and email authentication)
- CNAME Record — Creates an alias pointing one domain to another
Why Use DNS Lookup?
DNS lookup is a fundamental diagnostic tool for understanding how a domain is configured. It's useful for verifying DNS settings after making changes, troubleshooting email delivery issues, checking domain ownership, and understanding a website's infrastructure.
Frequently Asked Questions
This typically means the domain doesn't have the specific record type you're looking for, or the DNS servers haven't propagated the record yet. New DNS changes can take up to 48 hours to propagate globally.
You can look up any publicly registered domain name. However, some domains may have restricted DNS information or use specialized record types not displayed by this tool.
