DHCP for IPv4 and IPv6 both use these concepts. Basically, a scope is a collection of configuration information which will be used to provide configuration settings to devices on the network. A lease is a designation of how long the device on the network can use the provided information before having to request it again.
Feb 09, 2011 · As of Ubuntu version 11.04 Natty Narwhal, we have moved to ISC-DHCPv4, which now supports DHCP for IPv6, both as a server and as a client. DHCPv6 offers advantages over "traditional" stateless IPv6 autoconfigurations: as with IPv4, you can hand out specific addresses to clients and have them keep the same address throughout their lifetime. The Dynamic Host Configuration Protocol for IPv6 (DHCPv6) has been standardized by the IETF through RFC3315. DHCPv6 enables DHCP servers to pass configuration parameters, such as IPv6 network addresses, to IPv6 nodes. It offers the capability of automatic allocation of reusable network addresses and additional configuration flexibility. One of the more subtle differences between IPv4 and IPv6 is how DHCP is used by these two distinct network protocols. The recognizable fact is that DHCP for IPv4 (RFC 2132) is a completely separate protocol from DHCPv6 for IPv6 (RFC 3315). However, these protocols share some characteristics because, frankly, DHCP helped pave the way for DHCPv6. My network is running IPv6 with SLAAC and the JunOS version on my firewall does not support RDNSS, so I needed a full-featured DHCP server to hand out DNS information.. I already have a Raspberry Pi running isc-dhcp-server for my IPv4 network so I thought it would be simple to add IPv6 support. The subnet6 statement is used to provide dhcpd with enough information to tell whether or not an IPv6 address is on that subnet6. It may also be used to provide subnet-specific parameters and to specify what addresses may be dynamically allocated to clients booting on that subnet. Oct 29, 2018 · One way to specify an address range for IPv6 is to provide the beginning and ending addresses of the block: range6 2001:DB8::64 2001:DB8::C8 # This is the address range 100-200 in decimal Second Method. The second way to specify an address range for IPV6 is to use Classless Inter-Domain Routing (CIDR) notation to specify a block of addresses.

ISC DHCP ISC DHCP offers a complete open source solution for implementing DHCP servers, relay agents, and clients. ISC DHCP supports both IPv4 and IPv6, and is suitable for use in high-volume and high-reliability applications. DHCP is available for free download under the terms of the MPL 2.0 license. Note that currently, the ISC DHCP server can only serve IPv4 or IPv6, means you have to start the daemon twice (for IPv6 with option ”-6”) to support both protocols. Simple configuration Create a dedicated configuration file /etc/dhcp/dhcpd6.conf for the IPv6 part of the dhcpd. Sep 15, 2014 · DHCPv6 uses a DHCP Unique Identifier (DUID) where DHCP for IPv4 uses the MAC address of the client. DHCPv6 does not provide the IPv6 address of the default gateway to the client, this is provided by the ICMPv6 RA message. DHCP for IPv4 provides the default gateway IP address to the client.
IPv6 Prefix Options for Dynamic Host Configuration Protocol (DHCP) version 6. Category: Standards Track. Defines DHCPv6 options 25 (OPTION_IA_PD) and 26 (OPTION_IAPREFIX). DNS Configuration options for Dynamic Host Configuration Protocol for IPv6 (DHCPv6). Category: Standards Track.

The ISC DHCP includes support for IPv6 (DHCPv6) since the 4.x release with a DHCPv6 server, client and relay agent functionality. The server, client and relay agents support both IPv4 and IPv6. However, the client and the server can only manage one protocol at a time — for dual support they must be started separately for IPv4 and IPv6.
