arp是什么进程?

<p>ARP是<font face="Verdana">TCP/IP Arp command<br/></font></p>
<p><font face="Verdana"><a href="https://www.elecfans.com/soft/58/62/2008/200808317781.html">arp.exe</a> 是一个管理网卡底层物理地址的程序,每个网卡都有一个全球唯一的物理地址 <br/>,上网时,动态的IP地址就是根据这个物理地址影射的。 <br/>在同一个局域网段内有两个物理地址相同的网络适配器,不论如何配置都会造成IP地址 <br/>冲突。 <br/>arp -a,显示arp的影射; <br/>arp -s IP地址 物理地址,增加一个arp影射,如arp -s 192.168.1.1 00-aa-00-00-c2 <br/>-99; <br/>arp -d IP地址 物理地址,del掉一个arp影射。 <br/>用法:当IP地址冲突时,使用此命令可以把冲突的IP地址屏蔽掉! <br/>详细用法: <br/>displays and modifies the IP-to-Physical address translation tables used by <br/>address resolution protocol (ARP). <br/>ARP -s inet_addr eth_addr [if_addr] <br/>ARP -d inet_addr [if_addr] <br/>ARP -a [inet_addr] [-N if_addr] <br/>-a Displays current ARP entries by interrogating the current <br/>protocol data. If inet_addr is specified, the IP and Physical <br/>addresses for only the specified computer are displayed. If <br/>more than one network inteRFace uses ARP, entries for each ARP <br/>table are displayed. <br/>-g Same as -a. <br/>inet_addr Specifies an internet address. <br/>-N if_addr Displays the ARP entries for the network interface specified <br/>by if_addr. <br/>-d Deletes the host specified by inet_addr. <br/>-s Adds the host and associates the Internet address inet_addr <br/>with the Physical address eth_addr. The Physical address is <br/>given as 6 hexadecimal bytes separated by hyphens. The entry <br/>is permanent. <br/>eth_addr Specifies a physical address. <br/>if_addr If present, this specifies the Internet address of the <br/>interface whose address translation table should be modified. <br/>If not present, the first applicable interface will be used.Example: <br/>&gt; arp -s 157.55.85.212 00-aa-00-62-c6-09 .... Adds a static entry. <br/>&gt; arp -a .... Displays the arp table. <br/></p></font>
