DNS Lookup Tool
Check DNS records for any domain — A, AAAA, MX, NS, TXT, CNAME, SOA
How DNS Lookup Works
DNS (Domain Name System) is often called the phonebook of the internet. When you type a domain name like google.com, your computer queries DNS servers to find the corresponding IP address. This tool performs those queries and displays all available DNS records for a domain.
Understanding DNS Record Types
- A Record: Maps a domain to an IPv4 address (e.g., 142.250.190.14).
- AAAA Record: Maps a domain to an IPv6 address.
- MX Record: Specifies mail servers responsible for receiving email for the domain.
- NS Record: Indicates authoritative name servers for the domain.
- TXT Record: Stores text data, commonly used for SPF, DKIM, and domain verification.
- CNAME Record: Creates an alias pointing one domain to another.
- SOA Record: Contains administrative information about the zone.
Common Uses
DNS lookups are essential for verifying domain configuration, troubleshooting email delivery issues, checking DNS propagation after making changes, and auditing a domain's DNS setup for security purposes.
Frequently Asked Questions
What is a DNS lookup?
A DNS lookup queries the Domain Name System to find the IP address and other records associated with a domain name. It translates human-readable domain names like google.com into machine-readable IP addresses.
What are the different DNS record types?
Common DNS record types include: A (IPv4 address), AAAA (IPv6 address), MX (mail server), NS (name server), TXT (text information like SPF/DKIM), CNAME (alias to another domain), and SOA (start of authority with zone details).
How long does DNS propagation take?
DNS propagation typically takes 24-48 hours after making changes, though it can sometimes complete in minutes. The time depends on the TTL (Time to Live) values set for the records and how quickly DNS servers around the world update their caches.
