Hostname to IP Address

Resolve A (IPv4) and AAAA (IPv6) records for a hostname
Hostname to IP Address

Enter a hostname to resolve its A (IPv4) and AAAA (IPv6) records.

How hostname to IP lookup works

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.

Frequently asked questions

What does "hostname to IP" mean?
It means resolving a domain/hostname to its IP addresses using DNS records. IPv4 addresses usually come from A records, and IPv6 addresses from AAAA records.
Why do I see multiple IP addresses?
Many websites use load balancing and CDNs. DNS can return multiple IPs so traffic can be distributed across servers or regions.
Why does it return different IPs at different times?
DNS answers can change due to caching, geo-based routing, CDNs, and DNS TTL. Some domains intentionally rotate records for reliability.
What's the difference between A and AAAA records?
A records map a hostname to an IPv4 address. AAAA records map a hostname to an IPv6 address.
Does resolving a hostname reveal the real server IP?
Not always. If a site is behind a CDN or reverse proxy, DNS may point to the CDN/proxy edge IP rather than the origin server.
