NWA5120 Series User’s Guid e 189 A PPENDIX B IPv6 Overview IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The increase in IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 10 38 IP addresses.
Appendix B IPv6 NWA5120 Series User’s Guid e 190 Global Address A global address uniquely iden tifies a device on the Internet. It is similar to a “public IP address” in IPv4.
Appendix B IPv6 NWA5120 Series User’s Guid e 191 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).
Appendix B IPv6 NWA5120 Series User’s Guid e 192 combines its interface ID and global and subnet in formation advertised from the router . This is a routable global IP address.
Appendix B IPv6 NWA5120 Series User’s Guid e 193 such as the system name. The interface-ID option provides slot number , port information and the VLAN ID to the DHCPv6 server . The remote-ID option (if any) is stripped from the R elay-R eply messages before the relay agent sends the packets to the clients.
Appendix B IPv6 NWA5120 Series User’s Guid e 194 determine whether the destination address is on- link and can be reached directly without passing through a router . If the address is onlink, the addre ss is considered as the next hop. Otherw ise, the NW A determines the next-hop from the default rout er list or routing table.
