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. ----- eth0 Link encap:Ethernet HWaddr 00:A0:C9:xx:xx:xx UP BROADCAST MULTICAST MTU:1500 Metric:1 ... eth1 Link encap:Ethernet HWaddr 00:08:02:xx:xx:xx inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 ... lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 ... ppp0 Link encap:Point-to-Point Protocol inet addr:66.xxx.xxx.xxx P-t-P:66.xxx.xxx.xxx Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1492 Metric:1 ... 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?

IPv4 addresses in the 169.254/16 address space are part of the (reserved) "link local" IPv4 address space. OS environments allocate IPv4 addresses from the link local address space for a variety of reasons. For example, if DHCP fails to allocate an IPv4 address for a given network interface, the OS can try to allocate an unused link local IPv4 address (i.e., the proverbial "plan B"). If the link local address allocation is successful, the OS assigns the address to the network interface. (IOW, the OS assumes that it's better for the interface to have a link local IPv4 address than no IPv4 address at all.) > (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 are you asking the same questions again? If you don't understand the answers you were given then you should respond to those who answered you, and let them know that you need a simpler explanation of what is happening. Asking the exact same questions one week later indicate that you didn't read the helpful replies, and will cause others to just ignore you. -- -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |
