IPv6 addresses
An IPv6 address consists of a 48-bit global routing prex, optional 16-bit subnet ID, and a 64-bit interface identier in the extended
universal identier (EUI)-64 format.
IPv6 128-bit addresses are represented as a series of eight 16-bit hexadecimal elds separated by colons: x:x:x:x:x:x:x:x.
2001:0db8:0000:0000:0000:0000:1428:57a
Leading zeros in each eld are optional. You can also use two colons (::) to represent successive hexadecimal elds of zeros, but you can
use this short version only once in each address:
2001:db8::1428:57ab
In the following example, all the addresses are valid and equivalent:
• 2001:0db8:0000:0000:0000:0000:1428:57ab
• 2001:0db8:0000:0000:0000::1428:57ab
• 2001:0db8:0:0:0:0:1428:57ab
• 2001:0db8:0:0::1428:57ab
• 2001:0db8::1428:57ab
• 2001:db8::1428:57ab
IPv6 networks are written using CIDR notation. An IPv6 network (or subnet) is a contiguous group of IPv6 addresses the size of which
must be a power of two. The initial bits of addresses, which are identical for all hosts in the network, are the network's prex.
A network is denoted by the rst address in the network and the size in bits of the prex (in decimal), separated with a slash. Because a
single host is seen as a network with a 128-bit prex, host addresses may be written with a following /128.
For example, 2001:0db8:1234::/48 stands for the network with addresses 2001:0db8:1234:0000:0000:0000:0000:0000
through 2001:0db8:1234:ffff:ffff:ffff:ffff:ffff.
As soon as an IPv6 address is assigned, IPv6 packet processing is enabled on an interface. You can manually disable and re-enable IPv6
processing on an interface congured with an IPv6 address using the no ipv6 enable and ipv6 enable commands.
To remove all IPv6 addresses from an interface, use the no ipv6 address command. To remove a specic IPv6 address, use the ipv6
address
ipv6-address/mask command.
