怎么ifconfig和arp查到的自己IP会不一样？
搂主是不是搞错了。
ifconfig是显示当前网络的配置情况。
而arp是显示的arp协议所检测到的网络上的主机的ip.
以本人的机子为例：
root@ubuntu：# ifconfig
eth0
Link encap:Ethernet HWaddr 00:00:E2:53:31:03
inet addr:192.168.132.219 Bcast:192.168.132.255 Mask:255.255.255.0
inet6 addr: fe80::200:e2ff:fe53:3103/64 Scope:Link

RX bytes:24321752 (23.1 MiB) TX bytes:1235073 (1.1 MiB)

lo
Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1

TX packets:51 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:2876 (2.8 KiB) TX bytes:2876 (2.8 KiB)
由以上的信息可以看到我的ip地址是192.168.132.219。而下面的arp显示
root@ubuntu:# arp
Address HWtype HWaddress Flags Mask Iface
192.168.132.1 ether 00:0D:ED:DC:A3:80 C eth0
以上的arp显示的仅仅是arp检测到的默认网关的ip.
ifconfig是显示当前网络的配置情况。

红帽9书上是说 #arp -a命令查自己ipsurvival 写了：搂主是不是搞错了。
