struct Socket::IPAddress

Overview

IP address representation.

Holds a binary representation of an IP address, either translated from a String, or directly received from an opened connection (e.g. Socket#local_address, Socket#receive).

Example:

Socket::IPAddress.new("127.0.0.1", 8080)
Socket::IPAddress.new("fe80::2ab2:bdff:fe59:8e2c", 1234)

IPAddress won't resolve domains, including localhost. If you must resolve an IP, or don't know whether a String constains an IP or a domain name, you should use Addrinfo.resolve instead.

Defined in:

socket/address.cr
