ipconfig/ifconfig

Windows系统下使用ipconfig得到计算机的IP地址配置情况，在Linux/Unix下一般使用ifconfig
一、运行—CMD，在命令提示符下：
C:Documents and Settingslxiang>ipconfig /?
USAGE:
    ipconfig [/? | /all | /renew [adapter] | /release [adapter] |
              /flushdns | /displaydns | /registerdns |
              /showclassid adapter |
              /setclassid adapter [classid] ]
where
    adapter         Connection name
                   (wildcard characters * and ? allowed, see examples)
    Options:
       /?           Display this help message
       /all         Display full configuration information.
       /release     Release the IP address for the specified adapter.
       /renew       Renew the IP address for the specified adapter.
       /flushdns    Purges the DNS Resolver cache.
       /registerdns Refreshes all DHCP leases and re-registers DNS names
       /displaydns  Display the contents of the DNS Resolver Cache.
       /showclassid Displays all the dhcp class IDs allowed for adapter.
       /setclassid  Modifies the dhcp class id.
The default is to display only the IP address, subnet mask and
default gateway for each adapter bound to TCP/IP.
For Release and Renew, if no adapter name is specified, then the IP address
leases for all adapters bound to TCP/IP will be released or renewed.
For Setclassid, if no ClassId is specified, then the ClassId is removed.
Examples:
    > ipconfig                   ... Show information.
    > ipconfig /all              ... Show detailed information
    > ipconfig /renew            ... renew all adapters
    > ipconfig /renew EL*        ... renew any connection that has its
                                     name starting with EL
    > ipconfig /release *Con*    ... release all matching connections,
                                     eg. "Local Area Connection 1" or
                                         "Local Area Connection 2"
一般使用ipconfig /all得到计算机的计算机名称，计算机的网卡型号，网卡的地址，计算机配置的IP地址，子网掩码，网关地址，DNS服务器地址
二、在Linux下在shell中输入：ifconfig -a ，得到地址配置情况
[root@srun2 FreeBSD]# ifconfig -a

          inet addr:192.168.1.1  Bcast:192.168.1.255  Mask:255.255.255.0
