VERY Strange IP info???

[outty]

Hi guys,

I have a machine with 2 systems redhat7.3 and winXp installed( when boot, can switch).
I get IP from ISP via DSL in both system.

when use linux and use

ifconfig

to see IP info, it is OK.

when use winXP and use

ipconfig /all,

I will get the following info.

My questions are
(1)I use IP 66.xxx.xxx.xxx to access the Internet,
why and how did I get the 169.254.182.63
and 169.254.132.89?

(2)The Physical Address. . . . . . . . . : 00-55-98-00-00-00 related to my IP 66.xxx.xxx.xxx
is not 00-08-02-xx-xx-xx, nor 00-A0-C9-xx-xx-xx. WHY?

and How did I get 00-55-98-00-00-00?

(note: 00-08-02-xx-xx-xx and 00-A0-C9-xx-xx-xx are two net cards' Physical Addresses )

169.254.x.x is the default class assigned to a DHCP client when the
DHCP server cannot be contacted, noticed that in Linux eth0 you have
no ip on that interface, linux does not use these default address
range, it just does not initialize the ip at all, i think only
microsoft os uses it.
