IPv6 Subnet Masking, DHCPv6, Pv6 6to4 Mode

Page 90 highlights

Chapter 5 Broadband means that the first 32 bits (2001:db8) is the subnet prefix. IPv6 Subnet Masking Both an IPv6 address and IPv6 subnet mask compose of 128-bit binary digits, which are divided into eight 16-bit blocks and written in hexadecimal notation. Hexadecimal uses four bits for each character (1 ~ 10, A ~ F). Each block's 16 bits are then represented by four hexadecimal characters. For example, FFFF:FFFF:FFFF:FFFF:FC00:0000:0000:0000. DHCPv6 The Dynamic Host Configuration Protocol for IPv6 (DHCPv6, RFC 3315) is a server-client protocol that allows a DHCP server to assign and pass IPv6 network addresses, prefixes and other configuration information to DHCP clients. DHCPv6 servers and clients exchange DHCP messages using UDP. Each DHCP client and server has a unique DHCP Unique IDentifier (DUID), which is used for identification when they are exchanging DHCPv6 messages. The DUID is generated from the MAC address, time, vendor assigned ID and/or the vendor's private enterprise number registered with the IANA. It should not change over time even after you reboot the device. IPv6 6to4 Mode This mode also enables the Device to convert IPv6 packets to IPv4 packets. But instead of preconfiguring the destination router, you need to configure a 6to4 relay router that helps to route the packets to any IPv6 networks. In this mode, the Device should get a public IPv4 address for the WAN. The Device adds an IPv4 header to an IPv6 packet when transmitting the packet to the Internet. In reverse, the Device removes the IPv4 header from an IPv6 packet when receiving it from the Internet. An IPv6 address using the 6to4 mode consists of an IPv4 address, the format is as the following: 2002:[a public IPv4 address in hexadecimal]::/48 For example, 90 P-2812HNU(L)-Fx Series User's Guide
