What should I do if my IP address changes frequently?
If your IP address changes frequently, it may indicate that you are using a Dynamic IP address, which is common for most home network setups provided by Internet Service Providers (ISPs). A dynamic IP can change whenever your device reconnects to the network or periodically as assigned by your ISP. While this is normal for home networks, it can pose challenges for tasks like remote access or gaming.
In such cases, consider using a Dynamic DNS (DDNS) service. A DDNS enables you to associate a dynamic IP address with a static hostname, allowing it to remain consistent despite any changes. This can be particularly useful for accessing home servers or surveillance systems remotely. Additionally, if you need a static IP address for business purposes or specific applications, contact your ISP to inquire about upgrading to a plan that offers a static IP address.
