How do I update a public IP address?
Quick answer
To update a public IP address, you typically need to restart your modem or router, or request a new IP from your Internet Service Provider (ISP).
Updating a public IP address can be done through device restart or ISP request, depending on your connection type.
Steps
- 1
Restart Your Modem/Router
Unplug your modem/router from the power source, wait for 5-10 minutes, then plug it back in. This can often result in a new public IP address if your ISP uses dynamic IP addressing.

Contact Your ISP
If restarting does not change your IP address, contact your ISP and request a new public IP address. They may be able to assign one immediately or provide instructions.
Understanding Public IP Addresses
A public IP address is assigned by your ISP and is used to identify your network on the internet. It can be static (unchanging) or dynamic (changes periodically).
Methods to Update Your Public IP Address
You can update your public IP address by restarting your router or modem, or by contacting your ISP for a new assignment.
Watch out for
- Not all ISPs allow users to change their public IP address easily.
- Restarting your modem may not guarantee a new IP address if your ISP uses static IP addressing.
