Method: IP::Address::Util.unpack

Defined in:
lib/ip/util.rb

.unpack(ip) ⇒ Object

Take an ‘Integer’ type and return an IP::Address object.

This routine will ‘guess’ at what version of IP addressing you want, returning the oldest type possible (IPv4 addresses will return IP::Address::IPv4 objects).

In almost all cases, you’ll want to use the type-specific routines, which merely involve passing an Integer to the constructor for each class.
