A Record Lookup

Look up the IPv4 address a hostname resolves to, read straight from authoritative DNS rather than a cache.

Free, and no account needed. We read authoritative DNS live, never a cache.
About this tool. An A record maps a hostname to an IPv4 address — it's how browsers find your website. This lookup shows every A record for a name, including any CNAME alias chain it passes through on the way.

Ten signals decide whether your mail arrives. You just checked one.

An A record points at a web server. None of the records that decide whether your email is trusted live here.

How to read your A Record results

Common problems and how to fix them

Site does not load after a DNS change
The old A record may still be cached until its TTL expires. Confirm the new value here and wait out the TTL.
www works but the bare domain does not (or vice versa)
Each hostname needs its own record. Make sure both the apex and www resolve where you expect.

Common questions.
What is an A record?

It maps a hostname like www.example.com to an IPv4 address so browsers know which server to reach.

A record vs CNAME?

An A record points to an IP address. A CNAME points to another hostname, which is then resolved to an IP.
