NETGEAR 8800 User Manual Leading zeros in a four-digit group can be omitted. There is a special use of a double colon (::) in an address. The double colon stands for one or more groups of 16 bits of zeros and can only be used once in an address. For example, the following addresses: fe80:0:0:0:af34:2345:4afe:0 fe80:0:0:111:0:0:0:fe11 3c12:0:0:0:0:89:ff:3415 can be represented as: fe80::af34:2345:4afe:0 fe80:0:0:111::fe11 3c12::89:ff:3415 Additionally, you can specify an address in a mixed IPv4/IPv6 mode that uses six, four-digit hexadecimal numbers for the highest-order part of the address, and uses the IPv4 dotted decimal representation for the lowest-order remaining portion. For example: 0:0:0:0:0:0:192.168.1.1 0:0:0:0:0:ffff:10.0.14.254 These can be represented as: ::192.168.1.1 ::ffff:10.0.14.254 Both Global and Link-local IP addresses can be configured on a VLAN or tunnel interface, using the following commands: configure {vlan} ipaddress [ {} | ipv6-link-local | {eui64} ] configure tunnel ipaddress [ipv6-link-local | {eui64} ] where refers to the address specified in the above format. The IPv6 address configuration can be verified using the following commands: show vlan {detail {ipv4 | ipv6} | {ipv4 | ipv6} | virtual-router | stpd | security}show ipconfig ipv6 {vlan | tunnel } show ipconfig ipv6 {vlan | tunnel } Duplicate Address Detection When you configure an active interface with an IPv6 address, the interface must send out an advertisement containing its address. All other interfaces on the subnet have the opportunity to respond to the newly configured interface, and inform it that the address is a duplicate. Only after this process occurs, can the interface use the newly configured address. If the interface receives a message that the newly configured address is a duplicate, it cannot use the address. Until the Duplicate Address Detection (DAD) process completes, the new address is considered tentative, and will be shown as such in any display output. If the address is a Chapter 21.
