Detailed Description

IPv6 reservation for a host.

This class represents a reservation for a host of a single IPv6 address or prefix (in Host object).

The class holds the address and prefix length, a value of 128 for the latter implying that the reservation is for a single IPv6 address.

Constructor & Destructor Documentation

IPv6Resrv()

isc::dhcp::IPv6Resrv::IPv6Resrv	(	const Type &	type,
		const asiolink::IOAddress &	prefix,
		const uint8_t	prefix_len = 128
	)

Constructor.

Creates a reservation from the IPv6 address and prefix length value. If the prefix length is not specified, the default value of 128 is used. This value indicates that the reservation is made for an IPv6 address.

Parameters

type	Reservation type: NA or PD.
prefix	Address or prefix to be reserved.
prefix_len	Prefix length.

Exceptions

isc::BadValue

if prefix is not IPv6 prefix, is a multicast address or the prefix length is greater than 128.
