Hi, I've setup my sixxs tunnel successfully but I've got many IPv6 addresses: 1: lo: <LOOPBACK,UP,10000> mtu 16436 qdisc noqueue link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet 127.0.0.2/8 brd 127.255.255.255 scope host secondary lo inet 127.0.0.3/8 brd 127.255.255.255 scope host secondary lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:0e:0c:a1:b9:29 brd ff:ff:ff:ff:ff:ff inet6 fe80::20e:cff:fea1:b929/64 scope link valid_lft forever preferred_lft forever 3: isdn0d: <NOARP> mtu 512 qdisc noop qlen 10 link/[1000] 5: vlan2@eth0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc noqueue link/ether 00:0e:0c:a1:b9:29 brd ff:ff:ff:ff:ff:ff inet 192.168.200.1/24 brd 192.168.200.255 scope global vlan2 inet 192.168.200.121/32 scope global vlan2 inet 192.168.200.117/32 scope global vlan2 inet 192.168.200.116/32 scope global vlan2 inet 192.168.200.114/32 scope global vlan2 inet 192.168.200.113/32 scope global vlan2 inet 192.168.200.112/32 scope global vlan2 inet6 fe80::20e:cff:fea1:b929/64 scope link valid_lft forever preferred_lft forever 6: vlan3@eth0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc noqueue link/ether 00:0e:0c:a1:b9:29 brd ff:ff:ff:ff:ff:ff inet 10.7.99.10/24 brd 10.7.99.255 scope global vlan3 inet6 fe80::20e:cff:fea1:b929/64 scope link valid_lft forever preferred_lft forever 7: sit0: <NOARP> mtu 1480 qdisc noop link/sit 0.0.0.0 brd 0.0.0.0 8: vlan4@eth0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc noqueue link/ether 00:0e:0c:a1:b9:29 brd ff:ff:ff:ff:ff:ff inet 192.168.0.2/24 brd 192.168.0.255 scope global vlan4 inet 192.168.0.3/32 scope global vlan4 inet6 fe80::20e:cff:fea1:b929/64 scope link valid_lft forever preferred_lft forever 12: sixxs@NONE: <POINTOPOINT,NOARP,UP,10000> mtu 1280 qdisc noqueue link/sit 0.0.0.0 peer 193.109.122.244 inet6 2001:7b8:2ff:196::2/64 scope global valid_lft forever preferred_lft forever inet6 fe80::c0a8:3/64 scope link valid_lft forever preferred_lft forever inet6 fe80::c0a8:2/64 scope link valid_lft forever preferred_lft forever inet6 fe80::a07:630a/64 scope link valid_lft forever preferred_lft forever inet6 fe80::c0a8:c870/64 scope link valid_lft forever preferred_lft forever inet6 fe80::c0a8:c871/64 scope link valid_lft forever preferred_lft forever inet6 fe80::c0a8:c872/64 scope link valid_lft forever preferred_lft forever inet6 fe80::c0a8:c874/64 scope link valid_lft forever preferred_lft forever inet6 fe80::c0a8:c875/64 scope link valid_lft forever preferred_lft forever inet6 fe80::c0a8:c879/64 scope link valid_lft forever preferred_lft forever inet6 fe80::c0a8:c801/64 scope link valid_lft forever preferred_lft forever They are all link local (except the sixxs tunnel). I've read somewhere that they are used for internal communication on the link, is this true? Do I really need them; can I disable them? If yes, how (in Debian with /etc/interfaces). I'd prefer to setup static IP addresses. The next strange thing: As you can see, I've VLANs. Only eth0 has a link local inet6 address, all VLANs have the same! This should not be the case, should it? And finally, my last question: As you can see, the sixxs tunnel has all IPv4 addresses I've assigned to my devices attached as IPv6 addresses. Why? How can I disable this? I'm asking here because I'm new to IPv6 and so much addresses around are very confusing to me. I'd prefer to begin just with one address and add the others one by one by myself ;-) Thank you very much in advance, Niki
