Encontrar la dirección IP de un dominio

Use the lookup before a DNS migration to confirm which public addresses a hostname currently publishes.

Run it after CDN, hosting or load-balancer changes to compare expected edge addresses with live DNS answers.

Share it with support teams when users report that a domain reaches the wrong server or network path.

If the result is empty, confirm the hostname is public and has A or AAAA records. Some service names only publish CNAME records first.

If addresses differ from your provider dashboard, check TTL, split DNS, CDN flattening and whether you are looking at apex or www.

If only IPv4 or only IPv6 appears, verify whether the missing family is intentionally disabled for the service.

A records map a domain to IPv4 addresses, while AAAA records map it to IPv6 addresses. Browsers and clients may choose either family depending on network support.

CDNs often return provider edge addresses rather than origin server IPs. That is expected and usually protects the origin from direct exposure.

For a complete launch review, pair this tool with DNS Checker, SSL Certificate Checker and HTTP Header Checker.

dig is excellent for terminal users and resolver-specific diagnostics. DN01 gives a quick browser result with copy buttons and localized explanations.

DNS Checker shows many record types at once. Domain IP Lookup is narrower and easier when the only question is which IP addresses a domain resolves to.

WHOIS identifies registration data; it does not tell you the live A and AAAA addresses that clients use.
