A fixed IP address is an IP address that is assigned to a device and has the property that it does not change. The simcard can be accessed directly through the fixed IP address.
Fixed IP address security
A fixed public IP address is very vulnerable to security risks. It is accessible to all users on the internet and only depends on the authentication on the hardware. The big difference with a fixed private IP address is the approach. While a fixed public IP address can be accessed by any user on the internet, a fixed private IP address has a VPN tunnel. This means that all IP addresses are located within a VPN and cannot be accessed from outside. The user must first log in and can then connect to the fixed private IP address. This extra security has the advantage that devices do not have to be individually protected and the risks of external attacks are many times smaller.
