Why Does My IP Address Keep Changing?
If your IP address looks different from one day to the next, nothing is broken. Most home connections use dynamic addresses that rotate from time to time.

Why it happens
Internet providers own a pool of addresses and hand them out as needed. This is more efficient than permanently reserving one address per customer, so your address can change when your router reconnects, when your lease expires, or simply when the ISP reorganises its pool.
- You rebooted your router or it lost power.
- The address lease from your ISP expired and renewed.
- You switched networks, for example from Wi-Fi to mobile data.
- You connected to a VPN, which swaps in a different IP entirely.
Is a changing IP a problem?
For everyday browsing, no. You won't notice. It only matters if you're hosting something that needs a constant address, like a game server, a security camera you reach from outside, or remote access to a home computer.
How to get a fixed address
- Ask your ISP for a static IP. Many offer one, sometimes for a small fee.
- Use a dynamic DNS service, which keeps a hostname pointed at your changing IP automatically.
