IPv6 stack windowsXP problem

[António Amaral]

Dear All,   I am using IPv6 Windows XP stack and I have two questions:   1. Why it is created two IPv6 addresses on the Ethernet Interface? It should be created only one base on EUI-64, right? Next I show my interface output ----------------- Interface 4: Ethernet: Local Area Connection 14   Guid {DB7AA57C-5B0C-49B5-AAA0-6CC0E5A3CA08}   uses Neighbor Discovery   uses Router Discovery   link-layer address: 00-90-27-a7-0b-0b     preferred global 2001:690:2380:7770:ac34:34a:30d5:1aaa, life 6d19h33m46s/19h32m30s (temporary)     preferred global 2001:690:2380:7770:290:27ff:fea7:b0b, life 29d23h58m20s/6d23h58m20s (public)     preferred link-local fe80::290:27ff:fea7:b0b, life infinite     multicast interface-local ff01::1, 1 refs, not reportable     multicast link-local ff02::1, 1 refs, not reportable     multicast link-local ff02::1:ffa7:b0b, 5 refs, last reporter     multicast link-local ff02::1:ff8e:205d, 1 refs, last reporter     multicast link-local ff02::1:ffd5:1aaa, 4 refs, last reporter     multicast link-local ff02::1:ff16:8c70, 1 refs, last reporter   link MTU 1500 (true link MTU 1500)   current hop limit 128   reachable time 41000ms (base 30000ms)   retransmission interval 1000ms   DAD transmits 1   default site prefix length 48 ------   2. Why can I not ping to my IPv6 addresses? I can ping to others IPv6 addresses, and the others can ping my addresses. Is this a bug?   Thanks in advance   António Amaral
