A low-level module used by, among other things, the IO::Socket family of modules
Description
This module provides a variety of constants, structure manipulators and other
functions related to socket-based networking. The values and functions provided
are useful when used in conjunction with Perl core functions such as socket(),
setsockopt() and bind(). It also provides several other support functions,
mostly for dealing with conversions of network addresses between human-readable
and native binary forms, and for hostname resolver operations.
Some constants and functions are exported by default by this module; but for
backward-compatibility any recently-added symbols are not exported by default
and must be requested explicitly. When an import list is provided to the use
Socket line, the default exports are not automatically imported. It is
therefore best practice to always to explicitly list all the symbols required.
