Your NBG4104 router made by ZyXEL is the hub of your Wi-Fi network. Without it, you would not be able to spend countless hours diving deep into your Facebook or Youtube feed. However, that Wi-Fi network does not appear out of thin air, you first have to set up your router.
Your router's IP address could be considered the door to the interface, with the key being the username and password. The IP address, which is a private or local IP address, is also what allows other devices to connect to the router. Without the IP address, the ZyXEL NBG4104 router is nothing more than an ornament. As stated above, you can usually find the IP address of your router on the base of the unit or in the instructions, but there is another way, in case those two options do not work.
While scrolling through the menu to find your IP address, you may come across similar-looking numbers under different titles. That is because a router has two IP addresses, the private one detailed so far and a public one. Only you and the devices connected to the router can see the private IP address. All of those connected devices also have private IP addresses, which helps the router send information where it needs to go. As the private IP address gets used for the internal network, it is possible for other people, all over the world, to have the same private address, which will not affect your internet usage in any way.
On the other hand, the public IP address is visible to the websites you visit and gets used to transmit information from that website to the ISP, then on to your router, which use the above private IP addresses to send the data to the device on the network that requested it. For that reason, the public IP address is unique between users, with no router such as ZyXEL NBG4104 having the same public IP address at any one time. The ISP only has so many numbers to use, so your router gets assigned a new dynamic public IP address each time it connects to the internet. You can find your current public IP address by searching in Google for "what is my public IP address?"
Your public IP address can offer third parties a rough idea of your location, so many opt to use a VPN service, which will generate a random IP address to say you are browsing from somewhere you are not. You can use that same VPN service to view online content restricted by a location.
