IPv6 stack windowsXP problem

[Ant�nio 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   Ant�nio Amaral
