DNS Lookup
Check DNS records for any domain name.
What is DNS?
DNS (Domain Name System) is the internet's phone book. It translates human-readable domain names like "example.com" into IP addresses that computers use to locate each other.
When you type a URL in your browser, a DNS resolver queries multiple servers to find the IP address associated with that domain. This process typically takes milliseconds and happens entirely behind the scenes.
Different DNS record types serve different purposes: A records point to IPv4 addresses, MX records direct email, TXT records store verification data, and NS records delegate to authoritative name servers.
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. It translates human-readable names into machine-readable addresses.
What are the different DNS record types?
Common types include A (IPv4 address), AAAA (IPv6), MX (mail server), TXT (text data like SPF), NS (name server), CNAME (alias), and SOA (zone authority).
How long does DNS propagation take?
DNS propagation typically takes 1-48 hours globally, depending on TTL values and caching. Changes to NS records take longer than A or CNAME updates.
What is TTL in DNS?
TTL (Time to Live) is the duration in seconds that a DNS record is cached by resolvers. Lower TTL means faster propagation but more queries to your server.
