DNS Lookup
Query DNS records for any domain
Frequently Asked Questions
What is DNS lookup?
DNS lookup queries the Domain Name System to find the IP address associated with a domain name, or to retrieve other DNS records like MX, CNAME, and TXT records.
What are the different DNS record types?
A records map to IPv4, AAAA to IPv6, CNAME creates aliases, MX handles email routing, TXT stores text data (SPF, DKIM), and NS specifies name servers.
Why is DNS lookup slow?
Slow DNS lookups can be caused by overloaded DNS servers, long DNS chains, or missing cached records. Try using faster DNS like 1.1.1.1 or 8.8.8.8.
What is the difference between authoritative and recursive DNS?
An authoritative DNS server holds the actual DNS records for a domain. A recursive DNS server queries multiple authoritative servers on your behalf to resolve a domain name to an IP address.
How long does DNS propagation take after changing records?
DNS propagation typically takes 1-48 hours depending on TTL values. Records with low TTLs (300 seconds) propagate in minutes. Higher TTLs can delay propagation to up to 72 hours globally.
DNS Record Types
A Record: Maps a domain to an IPv4 address.
AAAA Record: Maps a domain to an IPv6 address.
MX Record: Specifies mail servers for the domain.
NS Record: Indicates the authoritative name servers.
TXT Record: Contains text data, often used for verification.
CNAME Record: Creates an alias pointing to another domain.
SOA Record: Contains administrative information about the zone.
