Enter a hostname to resolve its A (IPv4) and AAAA (IPv6) records.
DNS translates hostnames into IP addresses. A records return IPv4 addresses, while AAAA records return IPv6 addresses. Many domains return multiple IPs for redundancy and load balancing.
A hostname-to-IP lookup is most useful when you treat the output as live routing context, not as a guaranteed picture of the origin server. Many domains resolve to several addresses because of load balancing, failover, anycast, or CDN infrastructure. That means a single lookup can show different answers over time or from different resolvers without anything being wrong. The right question is usually not "why are there multiple IPs?" but "do these answers make sense for the service I expect to reach?"
Start by comparing and results. If a hostname only returns IPv4, an IPv6 connection problem may be normal rather than broken. If it returns both, differences in user experience can come from one stack being misconfigured. After you have the resolved IPs, continue with Reverse DNS to inspect hostnames, ASN Lookup to see which network announces the range, and WHOIS / RDAP if you need allocation or registrar context.
This layered workflow is especially important when a site sits behind Cloudflare, another CDN, or a reverse proxy. In those cases the resolved IP may belong to an edge network rather than the real origin. That is not a bug in the tool; it reflects how the hostname is intentionally exposed on the public internet. Pairing hostname resolution with IP location and reputation checks gives you a much safer interpretation than using the first returned IP alone.
