i tried to do an ipv6 install on my windows xp machine and i got this output:
Windows IP Configuration
Ethernet adapter Local Area Connection:
Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 10.80.104.245
Subnet Mask . . . . . . . . . . . : 255.255.252.0
IP Address. . . . . . . . . . . . : fe80::21a:6bff:fe47:b915%5
Default Gateway . . . . . . . . . : 10.80.104.1
i have some few questions:
1. what does the percentage (%) represent in the address format. is this the /prefix? i know ipv6 address format are in hex and colon (:)
2. are host PCs able to auto configure themselves for ipv6? is this a feature?
3. is this host doing a dual stack ip address scheme?
4. does a LAN ipv6 addresses always start with fe80?
1) I don't understand the % looks like a visualization error
However the FE80/10 are the link local addresses that are used on every LAN interface.
They provide a basis for communication over a network segment.
Of course this prefix is not routable.
Also routers use it for building adjacencies this is the case of OSPFv3
Here the host portion 64bits is made of the EUI transformation of the NIC MAC address.
3) yes it is dual stack
4) as told above fe80/10 is a special class of addresses used for link local on link communications. When connected to a network a NIC can get multiple ipv6 addresses including multiple private (unique local addresses) or public ipv6 addresses (Aggregatable global address)
Hope to help
