A Record Lookup Tool

An A record is the DNS entry that maps a hostname to an IPv4 address. It is the record most people think of when they say a domain “points at” a server. Use the form below to fetch the current A record for any domain and confirm the IPv4 address it resolves to.

What an A record does

When a browser wants to load example.com, it first asks a DNS resolver for the domain’s A record. The resolver walks the DNS hierarchy, finds the authoritative nameservers for the zone, and returns the IPv4 address the domain owner has published. The browser then opens a TCP connection to that IP and sends its HTTP request. Without a correct A record, nothing else — TLS, HTTP, redirects — ever gets a chance to run.

Common reasons to check an A record

• Verifying that a DNS change has actually taken effect after a hosting migration.
• Confirming that a domain resolves to the correct load balancer or CDN edge.
• Diagnosing “site not loading” complaints where the culprit is a stale or wrong DNS record.
• Auditing which IPs your own infrastructure exposes to the public internet.

Reading the result

The table returned by this tool shows the record type (always A here), the host being queried, the TTL (how long resolvers may cache the answer, in seconds), and the IPv4 address itself. A domain can publish multiple A records; DNS clients typically round-robin between them, which is a simple form of load balancing.
