.. _OcaIP4Address:

OcaIP4Address
=============

.. cpp:type:: OcaIP4Address = OcaString

    IP version 4 network address in string form "x1.x2.x3.x4" where the x's are
    decimal integers in the range 0...255.

.. _OcaIP4AddressAndPrefix:

OcaIP4AddressAndPrefix
======================

.. cpp:type:: OcaIP4AddressAndPrefix = OcaString

    IP version4 address prefix in string form "x1.x2.x3.x4/n" where the x's are
    decimal integers in the range 0...255, and n is an integer in the range
    0...31. n specifies the number of bits occupied by the prefix. This
    construct replaces the conventional IPv4 address + subnet mask. Examples
    123.456.789.001 / 16 = 123.456.789.001 + 255.255.0.0 123.456.789.001 / 24 =
    123.456.789.001 + 255.255.255.0

.. _OcaIP4Gateway:

OcaIP4Gateway
=============

.. cpp:struct:: OcaIP4Gateway

    Descriptor of an IPV4 gateway

    .. cpp:member:: OcaIP4AddressAndPrefix DestinationPrefix

    .. cpp:member:: OcaUint16 Metric

.. _OcaIP4AutoconfigMode:

OcaIP4AutoconfigMode
====================

.. cpp:enum:: OcaIP4AutoconfigMode : uint8_t

    Autoconfiguration mode

    .. cpp:enumerator:: None = 0

        No autoconfig - manual address entry

    .. cpp:enumerator:: DHCP = 1

        DHCP

    .. cpp:enumerator:: DHCP_LINKLOCAL = 2

        DHCP with link-local fallback

    .. cpp:enumerator:: LINKLOCAL = 3
