Double IPv6 addresses on one machine! Help


im running centos 5.5 and i got two ipv6 addresses.

inet6 addr: fe80::20c:xxxx:xxxx:xxxx/64 Scope:Link
inet6 addr: fd00::xxxx:xxxx/64 Scope:Global

the fe80 addrress is the unique address formed by the machine itself using stateless autoconfiguration.

the fd00 address was the address config'd by me manually because i want the apache to listen to this address.

both addresses are shown in the ifconfig, but when i open my windows and run cmd to test ping, i only can ping the fe80 address.

why it cannot ping fd00 address? i do not need fe80 address bacause of the apache issue. i want the unique ipv6 address of my machine to be the fd00 address. Help me.

Hello,

Do you know what devices the IP addresses are allocated to? If not, can you please post the output of the following command, using code tags? Thanks!
Code:
ifconfig -a
Cheers,

Josh

All this means is that the scope for that interface is both local, and global. Have you tried pinging the global scope from outside of your LAN?
