The result of this test which took 10 minutes (the batch file seems to still be running):

Strange, only one IP and MAC were scanned

My computer has no restrictions at all! This local area network, I am the network administrator!!!!!

```
@echo off
arp -d
for /l %%i in (0,1,128) do ping 192.168.1.%%i -n 1 >nul
arp -a >11.txt
arp -d
for /l %%i in (128,1,255) do ping 192.168.1.%%i -n 1 >nul
arp -a >>11.txt
arp -d
```

CODE:
--------------------------------------------------------------------------------

@echo off
set/p=>list.txt<nul
for /l %%a in (1,1,254) do (
echo.&echo.
for /f "delims== tokens=2" %%i in ('nbtstat -A 192.168.0.%%a^|find "MAC Address"') do (
echo==========================>>list.txt
echo %%i=======192.168.0.%%a >>list.txt
)
)
pause
start list.txt
goto :eof

Now it's okay, but it's extremely slow!!!!

I understand, thank you!

Oh no, I taught the technology to the Japanese.

Scanning MAC without nbtstat

Using ping -n 1 -w 10 IP first, then arp -a | find "IP" is a better solution

Because using ping can quickly detect the connection

Command line solution

for /l %l in (1,1,254) do @(ping -n 1 -w 10 192.168.0.%l>nul && arp -a | find " 192.168.0.%l ")

Sorry, just saw the plan of 9527, mine is invalid.

I don't know how large the ARP table of WIN can be?

In fact, the MAC table obtained by relying on IP with batch processing commands cannot guarantee authenticity.

Batch processing also requires the support of system services.
For example, in my company's local area network, all are single - machine Internet access, no sharing is needed, the Server service is not even started, and it accesses the Internet through a router, with DHCP automatically obtaining the IP. In this case, I think this batch processing has no use.
