Subnet::IPv6::Loopback

Inherits Subnet::IPv6 / Comparable / Enumerable / Subnet / Reference / Object

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 its appropriate prefix,

::1/128

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

ip = Subnet::IPv6::Loopback.new

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.

Constructors

new(bla = nil)

Creates a new IPv6 loopback address

ip = Subnet::IPv6::Loopback.new

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