Hostname to IP Lookup

Enter any server hostname or domain name to resolve its corresponding public IPv4 and IPv6 network addresses.

How Hostname to IP Resolution Works

When you enter a web address into a browser, network routers cannot communicate using textual names directly. Hostname resolution bridges human readability and network addressing through the Domain Name System (DNS).

WHAT IS A HOSTNAME?

A hostname is a human-readable label assigned to a device on a network (such as mail, ftp, or www). When combined with a domain name, it creates a Fully Qualified Domain Name (FQDN).

RESOLVING TO IP ADDRESSES

During a forward DNS lookup, recursive resolvers translate your target hostname into its assigned IPv4 (32-bit) or IPv6 (128-bit) address, allowing data packets to route across the web.

A RECORDS

Maps a hostname to an IPv4 numerical address (e.g., 192.0.2.1). This is the standard mapping used across global networks.

AAAA RECORDS

Maps a hostname to a 128-bit IPv6 hexadecimal address (e.g., 2001:db8::8a2e:370:7334) for modern web routing.

CNAME ALIASES

Aliases one host to another canonical hostname rather than binding directly to an IP, allowing multiple services to share dynamic IPs.
