Your IP Address is your number on the Internet. It's similar to your home address or personal cell phone number.

IPv4 is the bulk of the internet. It is comprised of four sets of numbers that range from 0 - 255. Example 1.1.1.1.

IPv6 is required today because all the addresses for IPv4 is exhausted, meaning they've all been given out. IPv6 is hexadecimal with eight sets and ranges from 0 to FFFF. Example 2606:4700:4700::1111.

macOS, Windows, Linux

If you're on macOS or Linux open Terminal.

If you're on Windows open PowerShell

  • Enter curl -4 ifconfig.me to get your IPv4 address.
  • Enter curl -6 ifconfig.me to get your IPv6 address. 
┌[ jake@macOS ] ~
└➤ curl -4 ifconfig.me
1.1.1.1%
┌[ jake@macOS ] ~
└➤ curl -6 ifconfig.me
2606:4700:4700::1111%

Finding your IPv6 Network

Your IPv6 address may look long such as 2600:6c3a:7c3a:5de0:ca06:fba0:2f00:bbc2. You will need to truncate it at the fourth group 2600:6c3a:7c3a:5de0 and add ::/64. In our example it will be 2600:6c3a:7c3a:5de0::/64.
