Understanding Why Your IP Address Changes and How to Set a Static IP

Are you concerned about your constantly changing IP address? This MiniTool guide explains why this happens and shows you how to configure a static IP address.

Understanding IP Addresses

Most home users receive their IP addresses from their Internet Service Provider (ISP). Upon account creation, the ISP automatically assigns a unique IP. Fortunately, the technical details are handled automatically by your computer's network hardware, modem, and TCP/IP software—it's essentially plug-and-play.

ISPs generally use dynamic IP addresses, which can change. Static IP addresses are also available, offering a permanent address. For a detailed comparison, see our guide: Static vs. Dynamic IP: Differences and How to Check.

Why Your IP Address Changes

The internet's vast number of users necessitates dynamic IP addresses. Assigning a static IP to every user would be incredibly expensive and impractical, especially given the limitations of the IPv4 system.

Dynamic IP addresses are "borrowed" each time you connect, making IP address management more efficient for ISPs. While you might not notice changes frequently, they can occur, particularly when changing routers.

Using dynamic IPs simplifies ISP operations. Even if you move, your ISP doesn't need to reassign your IP. You'll automatically receive a new dynamic IP in your new location.

Your IP address is tied to your network, not just your computer. Switching Wi-Fi networks will change your IP address because your device is borrowing a new address from the new network.

Setting Up a Static IP Address (Windows 10)

If you prefer a consistent IP address, follow these steps to set up a static IP in Windows 10:

Step 3: Under Ethernet, click Properties. (Avoid selecting Wi-Fi.)

Step 4: Locate the IP settings section and click Edit.

Step 5: Change IP assignment from Automatic (DHCP) to Manual and enable IPv4.

Step 6: Enter your static IP address, subnet mask, default gateway, and preferred DNS server.

Step 7: Click Save to apply the changes.

A changing IP address is usually nothing to worry about. However, if you need a consistent IP, setting a static IP is straightforward. Remember to back up your data beforehand, using a tool like MiniTool ShadowMaker for added security.
