Quickly Find Used IP Addresses
Instead of manually pinging all IP addresses on your LAN you can use this nice command:
Open Command Prompt and type:
FOR /L %i IN (1,1,254) DO ping -n 1 192.168.0.%i | FIND /i "Reply">> c:\ipaddresses.txt
The “-n 1” is for only 1 ping packet to be sent to each computer.
Passwords Haven’t Disappeared Yet
123456. Qwerty. Iloveyou. No, these are not exercises for people who are brand new to typing. Shockingly, they are among the most common passwords that end users choose in 2021. Research has found that the average business user must manually type out, or copy/paste, the credentials to 154 websites per month. We repeatedly got one question that surprised us: “Why would I ever trust a third party with control of my network?
Change 192.168.0 to match you own Network ID.
This will ping all IP addresses on the 192.168.0.0 network segment and create a text file called IPADDRESSES.TXT in C:\, where it will list only the IP addresses that gave a reply.
You can also add a -a to the PING command to resolve all the responding IP addresses to HOST names, but doing so will cause the script to take a considerable time to finish:
FOR /L %i IN (1,1,254) DO ping -a -n 1 192.168.0.%i | FIND /i "Reply">> c:\ipaddresses.txt
You can, of course, modify this script and make it suit your own desire.
