inet 127.0.0.1 netmask ff000000
lo0:1: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
zone udi
inet 127.0.0.1 netmask ff000000
elxl0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2

方法2:
/usr/sbin/arp -a (普通用户可以运行)
----------------------------------------------------------------------------------
-bash-3.00$ arp -a | grep `hostname` | awk '{print $5}'

方法3:
/bin/netstat (普通用户可以运行)
----------------------------------------------------------------------------------
