An easy way to check if the IP Address allocated to your home network is Static or Dynamic is by calling your Internet service provider (ISP) and by calling the sysadmin or IT support; if you are at school, college, university or place of work.
In addition to this, you can check if your IP Address is Static or Dynamic by using a number of other methods as provided below in this guide.
Check If Your IP is Static or Dynamic
If you are using a Windows computer, you can check whether you are using a Dynamic or Static IP type of IP Address by running the “ipconfig” command.
Similarly, you can check if your IP Address is static or dynamic by going to System Settings on a MacBook and by tapping on the name of your Wi-Fi network on a mobile device.
1. Check If IP Static or Dynamic on Windows computer.
If you are using a Windows computer, you can check if you are using a static or dynamic type of IP Address by using Command Prompt.

3. On Command Prompt screen, type ipconfig /all and press the Enter key on the keyboard of your computer to run this command.

4. Once the command is executed, scroll down and locate DHCP Enabled line and read the word next to it.
