.create ⇒ Object

The address with all zero bits is called the unspecified address

(corresponding to 0.0.0.0 in IPv4). It should be something like this:

  0000:0000:0000:0000:0000:0000:0000:0000

but, with the use of compression, it is usually written as just two
colons:

  ::

or, specifying the netmask:

  ::/128

With IPAddress, create a new unspecified IPv6 address using its own
subclass:

  ip = IPAddress::IPv6::Unspecified.new

  ip.to_s
    # => => "::/128"

You can easily check if an IPv6 object is an unspecified address by
using the IPv6# unspecified? method

  ip.unspecified?
    # => true

An unspecified IPv6 address can also be created with the wrapper
method, like we've seen before

  ip = IPAddress "::"

  ip.unspecified?
    # => true

This address must never be assigned to an interface and is to be used
only in software before the application has learned its host's source
address appropriate for a pending connection. Routers must not forward
packets with the unspecified address.

Creates a new IPv6 unspecified address

  ip = IPAddress::IPv6::Unspecified.new

  ip.to_s
     # => => "::/128"
