What is an A record lookup?

An A record lookup queries DNS for type A records and returns the IPv4 addresses associated with a hostname.

How do I find a website IP address?

Enter the domain in the A record lookup tool and click Lookup A Records. The Value column shows each published IPv4 address.

An A (Address) record maps a DNS name to one or more 32-bit IPv4 addresses used for web, mail, and application traffic.

Yes. Load balancing, anycast, and round-robin setups often publish several A records for the same hostname.

TTL (time to live) is how long resolvers may cache the answer in seconds. Lower TTL speeds up DNS change propagation.

Ping uses DNS resolution plus routing. CDNs, geo DNS, and anycast may return different edges. Always compare live A answers from DNS.

They are separate names in DNS. Check both if users reach your site via www.example.com and example.com.

DNS Lookup returns many record types at once. This page focuses only on A records for a faster IPv4-specific answer.

Inbound mail uses MX records, not A records. A records matter for websites and services reached by hostname over IPv4.

The name may use only AAAA (IPv6), a CNAME alias, or have no address published. Try the apex, www, or AAAA lookup.

Changes propagate after TTL expires on cached resolvers. Publishing a lower TTL before a migration reduces wait time.

Often the A record points to the CDN edge network rather than your origin. That is expected when a proxy is enabled.

Yes. IP Checker Online provides this tool at no cost with no account required.

A records hold IPv4 addresses. AAAA records hold 128-bit IPv6 addresses. Dual-stack sites may publish both.

After DNS edits, before firewall allowlists, during CDN or hosting migrations, and when debugging unreachable websites.
