The loopback address is a unicast localhost address. If an

application in a host sends packets to this address, the IPv6 stack
will loop these packets back on the same virtual interface.

Loopback addresses are expressed in the following form:

  ::1

or, with their appropriate prefix,

  ::1/128

As for the unspecified addresses, IPv6 loopbacks can be created with
IPAddress calling their own class:

  ip = IPAddress::IPv6::Loopback.new

  ip.to_string
    # => "::1/128"

or by using the wrapper:

  ip = IPAddress "::1"

  ip.to_string
    # => "::1/128"

Checking if an address is loopback is easy with the IPv6# loopback?
method:

  ip.loopback?
    # => true

The IPv6 loopback address corresponds to 127.0.0.1 in IPv4.

Creates a new IPv6 unspecified address

  ip = IPAddress::IPv6::Loopback.new

  ip.to_string
    # => "::1/128"
