这个：检索LAN的IP和MAC地址 [ ^ ]比您想要的更多 - 它检索IP和MAC地址，但您可以使用GetHostByAddress [ ^ ]从IP获取主机名。
This: Retrieving IP and MAC addresses for a LAN[^] does rather more than you want - it retrieves the IP and MAC addresses, but you can use GetHostByAddress[^] to get the host name from the IP.
您可以在计算机上安装nmap并让它来询问你的网络。有关它的信息可以在这里找到。
此工具将告诉您网络上的节点，MAC地址以及重新打开的端口。如果我的网络是192.168.1。*，我将使用的命令是
nmap -sP 192.168.1.0/24
扫描我的网络并报告其上的所有节点。
You can install nmap on your machine and get it to inquire about your network. Info about it can be found here.
This tool will tell you what nodes are on your network, their MAC address and what ports re open. If my network is 192.168.1.*, the command I would use is
nmap -sP 192.168.1.0/24
which scans my network and reports on all nodes on it.
