A static IP address is a public IP address that remains the same for a given device. Normally, a public IP address is assigned at random to computers and other devices that connect to the internet. In contrast, a dynamic IP address changes. For  a dynamic IP addresses, the refresh interval is 7 days but, it may be more or less depending on your ISP. If you want a static IP address, you will likely have to get in touch with your ISP, or a similar governing authority to get it. You cannot simply pick a static IP for yourself.

How you get a static IP will differ from country to country. The laws and regulatory authorities of a country will dictate the process that’s involved in getting a static IP. If you’re unsure of how to get one in your country, start by talking to your ISP. Even if your ISP cannot give you a static IP address, it can probably guide you on how to get one.
