host_address/3

Availability::- use_module(library(socket)).(can be autoloaded)

Translate between a machines host-name and it's (IP-)address. Supported options:

domain(+Domain): One of inet or inet6 to limit the results to the given family.
type(+Type): One of stream or dgram.
canonname(+Boolean): If true (default false), return the canonical host name in the frist answer

In mode (+,-,+) Address is unified to a dict with the following keys:

address: A Prolog terms describing the ip address.
domain: One of inet or inet6. The underlying getaddrinfo() calls this family. We use domain for consistency with socket_create/2.
type: Currently one of stream or dgram.
host: Available if canonname(true) is specified on the first returned address. Holds the official canonical host name.
