What is DNS Lookup – Check DNS Records Free Online?
A DNS lookup tool queries the Domain Name System to retrieve records associated with a domain name. DNS translates human-readable domain names into IP addresses and stores other metadata like mail server addresses (MX), name servers (NS), and verification tokens (TXT). Irreva's DNS Lookup uses the Google Public DNS API directly from your browser - no data passes through Irreva servers.

Frequently Asked Questions
What is a DNS lookup?
A DNS lookup queries the Domain Name System to resolve a domain name to its associated records — IP addresses (A/AAAA), mail servers (MX), name servers (NS), text records (TXT), etc.
What is the difference between A and AAAA records?
A records map a domain to an IPv4 address (e.g. 93.184.216.34). AAAA records map to an IPv6 address (e.g. 2606:2800:220:1:248:1893:25c8:1946). Most sites have both.
What are MX records used for?
MX (Mail Exchange) records specify which mail servers handle email for a domain. The priority number determines the order servers are tried — lower number = higher priority.
What are TXT records used for?
TXT records store arbitrary text. They are commonly used for domain verification (Google, Microsoft), SPF email authentication, DKIM signatures, and DMARC policies.
What does TTL mean?
TTL (Time To Live) is the number of seconds a DNS record can be cached before resolvers must re-query for fresh data. Shorter TTL means faster propagation of changes; longer TTL reduces DNS query load.
Why do DNS changes take time to propagate?
DNS changes propagate as cached records expire based on their TTL values. With a 3600s (1 hour) TTL, resolvers worldwide can serve the old record for up to 1 hour after a change.
