谁帮我看一下这是什么意思？

arp -a命令查看主机保存的所有的MAC地址表
interface显示的是你的IP地址。
下面的列表是MAC地址和IP地址的对应列表。
比如第一项，说明IP192.168.0.88对应MAC地址00-50-7f-03-3a-66 dynamic说明IP是动态分配的。

Displays and modifies the IP-to-Physical address translation tables used by
address resolution protocol (ARP).

ARP -s inet_addr eth_addr [if_addr]
ARP -d inet_addr [if_addr]
ARP -a [inet_addr] [-N if_addr]

-a Displays current ARP entries by interrogating the current
protocol data. If inet_addr is specified, the IP and Physical
addresses for only the specified computer are displayed. If
more than one network interface uses ARP, entries for each ARP
table are displayed.
-g Same as -a.
inet_addr Specifies an internet address.
-N if_addr Displays the ARP entries for the network interface specified
by if_addr.
-d Deletes the host specified by inet_addr. inet_addr may be
wildcarded with * to delete all hosts.
-s Adds the host and associates the Internet address inet_addr
with the Physical address eth_addr. The Physical address is
given as 6 hexadecimal bytes separated by hyphens. The entry
is permanent.
eth_addr Specifies a physical address.
if_addr If present, this specifies the Internet address of the
interface whose address translation table should be modified.
If not present, the first applicable interface will be used.
Example:
> arp -s 157.55.85.212 00-aa-00-62-c6-09 .... Adds a static entry.
> arp -a .... Displays the arp table.

Interface:192.168.0.10 ---0x2 表示本机的IP地址

Internet Address Physical Address Type
192.168.0.88 00-50-7f-03-3a-66 dynamic 表示与IP为192.168.0.88的设备连通,它的MAC地址是 00-50-7f-03-3a-66

192.168.0.186 00-20-ed-16-8c-bd dynamic 同上

另:arp /a这个命令其实是显示与本机连通的设备的IP地址,以及对应的MAC地址
