An IP address (Internet Protocol Address) is a unique «passport» for your device on the internet. It identifies you on the network, lets you receive and send data, open websites and use online services. Without an IP address, a device simply cannot connect to the internet.
Dynamic IP addresses are addresses that the internet provider assigns to a user automatically every time they connect to the network. They can change after a router reboot or after a certain period of time.
Such addresses are convenient for most users — they require no configuration and allow the address space to be used more economically.
External IP addresses are unique addresses that the provider gives your connection for internet access. They are visible to every resource on the network and make it possible to identify a user outside the local network.
It is precisely thanks to an external IP address that you can connect to servers or video surveillance cameras and set up remote access.
Static IP addresses are permanent addresses that the internet provider assigns to a specific user or device. They do not change after reconnecting to the network or rebooting the equipment.
