IPv4 and IPv6

IPv4 addresses are 32-bit numbers, usually written as four decimal octets (e.g. 192.168.1.1). IPv6 addresses are 128-bit, written as eight groups of hex digits with colons; compression with :: is allowed (e.g. ::1 for localhost).

About IP Validator

The IP Validator checks whether a string is a valid IPv4 or IPv6 address. For valid addresses it shows the type (IPv4 or IPv6) and a normalized form. This is useful when configuring servers, validating user input, or writing scripts that work with IP addresses.
