Sorry for yet again another stupid v6 question. (I'm full of them =] )
I had OpenSUSE's network settings set up using Yast's Network Settings panel. I ended up discovering a bug. It appears that even though I set OpenSUSE to request v6 addresses with SLAAC only, it still requests addresses via DHCPv6. The result of my interface config was this:
gundam:~ # ifconfigeth0 Link encap:Ethernet HWaddr 50:E5:49:C1:83:78 inet addr:172.20.1.108 Bcast:172.20.1.255 Mask:255.255.255.0 inet6 addr: 2601:d:3880:11:52e5:49ff:fec1:8378/64 Scope:Global inet6 addr: 2601:d:3880:11:80d7:7bcc:1485:65a/64 Scope:Global inet6 addr: 2601:d:3880:11:c508:dc5e:a918:57f1/64 Scope:Global inet6 addr: 2601:d:3880:11:3c86:22dc:e4f7:839c/64 Scope:Global inet6 addr: 2601:d:3880:11:a40e:d555:4c3e:ea7f/64 Scope:Global inet6 addr: fe80::52e5:49ff:fec1:8378/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:872030 errors:0 dropped:14 overruns:0 frame:0 TX packets:414056 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:808085470 (770.6 Mb) TX bytes:57711644 (55.0 Mb)
All of the v6 addresses were functioning properly and were able to be accessed from the internet. I'm 100% sure that there are no DHCPv6 servers alive on my local network.
If it normal behavior for Comcast to keep handing out single v6 addresses if requested by a device on a single customer network? It might just be the v4 thinking in me, but it seems like strange behavior.
