windows 使用batch 指令匯出dhcp lease位址租用紀錄

 如果是windows2012，powershell 4.0裡面有get-dhcp的指令把DHCP目前租用IP的清單做匯出。

但在windows2008，powershell 1.0沒這個指令，不想升級powershell，可以用netsh來完成，指令如下:

@echo off

netsh dhcp server scope 172.16.11.0 show clients > "%DATE:~0,4%%DATE:~5,2%%DATE:~8,2%_dhcp_clients.txt"

exit

指令會把172.16.11.0這個領域的IP租用匯出到txt中，檔名是會以當天的日期呈現。

如果要把每個領域都匯出，就把指令重覆貼上，改掉scope後面的領域IP就行了。

If you are using Windows 2012, PowerShell 4.0 includes the get-dhcp command to export a list of currently leased IP addresses from DHCP.

However, in Windows 2008, PowerShell 1.0 does not have this command. If you do not want to upgrade PowerShell, you can use netsh to complete the task. The command is as follows:

@echo off

netsh dhcp server scope 172.16.11.0 show clients > "%DATE:~0,4%%DATE:~5,2%%DATE:~8,2%_dhcp_clients.txt"

exit

This command will export the IP leases for the 172.16.11.0 scope to a text file. The file name will be in the format of YYYYMMDD_dhcp_clients.txt.

To export leases for all scopes, simply copy and paste the command, and change the scope IP address after scope.
