Along with the Network
Address Translation Protocol (NAT), DHCP is a protocol designed to
conserve IP address space. In
DHCP, users share IP addresses, so more addresses are available for
other users. This type of
conservation is not needed with 128 bytes of address length!
The new modification of DHCP,
DHCP for IPv6 will be used almost exclusively for greater network
management flexibility. Improvements
for DHCP for IPv6 include its exploitation of IP6’s multicast
addressing to be able to change the configuration parameters of multiple
interfaces that are referenced by a particular multicast addresses.
With DHCP IPv4, the network was dynamic, but the nodes could only
change one-by-one. With the
new multicast addressing, the network will be increasingly more
flexible. DHCP for IPv6
will be increasingly more convenient to the Network Administrator.
BOOTP (the antiquated address-allocation protocol) backward
compatibility will no longer be necessary.
Also, there will be an Autoconfigure property in the new DHCP.
Today, if a new interface is put into a network, a human being
still has to configure the interface to work within the network.
DHCP IPv6 will have greater capability, and will autoconfigure
the new interface appropriate to the network, apart from specifying its
IP address.
