DNS Checker
Look up A, AAAA, MX, TXT, CNAME, NS, SOA and PTR records for any domain.
About this tool
The DNS Checker queries the authoritative DNS system for any domain and returns the records currently being served. Pick a record type such as A (IPv4 address), AAAA (IPv6 address), MX (mail exchanger), TXT (text/verification records), CNAME (alias), NS (name servers), SOA (zone authority) or PTR (reverse pointer) and get the values, TTLs and query time.
Use this tool when you are migrating hosting, configuring email, verifying domain ownership records, or debugging why a service cannot find your domain. Results come directly from live DNS resolution, so what you see is what the rest of the internet sees.
Frequently asked questions
What is a DNS record?
A DNS record is an instruction stored in the Domain Name System that maps a domain name to information such as an IP address (A/AAAA), a mail server (MX) or arbitrary text (TXT). Resolvers read these records to find your website and email servers.
What does TTL mean?
TTL (Time To Live) is the number of seconds a resolver may cache a DNS answer before asking again. A low TTL (e.g. 300) makes changes propagate quickly; a high TTL (e.g. 86400) reduces DNS traffic but slows down changes.
Why do I see different results than my computer?
Your operating system and ISP cache DNS answers. If you recently changed a record, your local cache may still hold the old value until the TTL expires. This tool performs a fresh query, so it usually reflects changes sooner.
