The full IPv6 prefix is 64 bits long and is made up of an address scope prefix, a router ID prefix and a 16-bit block for a subnet number. the remaining 64 bits are for the host address which is required to be a full 64 bits long.
Feb 08, 2011 · That is it for DHCP in IPv6, you’ll find that doing dynamic addressing in IPv6 to be a preference over typing in IPv6 static addresses into systems. In my upcoming blog posts on IPv6, I will cover: Jul 24, 2020 · IPV6 DHCP Server configuration on a Cisco device is very similar to a normal, IPV4 configuration, but there is a big difference that you will want to make sure to not miss. Everything can be broken down into the following three steps: Create the IPV6 DHCP Pool Configure \ Apply the pool to an interface Configuration of the ISC DHCP server for IPv6 (dhcpd) 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. 22.6.1.1. 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 version 6 (DHCPv6) is a network protocol for configuring Internet Protocol version 6 (IPv6) hosts with IP addresses, IP prefixes and other configuration data required to operate in an IPv6 network. It is the IPv6 equivalent of the Dynamic Host Configuration Protocol for IPv4.
IPv6 is different and with enhanced protocols like Stateless Address Auto-configuration (SLAAC) 2, DHCP concepts and best practices will also change. In this article we will begin to outline some of the fundamental differences between the two versions, explore historical uses of DHCPv4 and how those concepts will adapt/change in IPv6. DHCP functions the same, but the specifics are adapted for IPv6 and to disambiguate, it is known as DHCPv6; there is a separate RFC: RFC-3315. IPv6 Autoconfiguration During the design of IPv6, then codenamed ‘IPng’, the design of “autoconfiguration” for IP was refactored to support a more automated method by which hosts could join an

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.
