On the vast global network, every device has an IP (Internet Protocol) address. is the IP address that represents your computer, mobile phone or any other network device on the Internet or local network. It’s different than other addresses because it’s in the range of IP addresses that are reserved for local area networks only (private IP addresses). This address is also unique, which means that only one device can have it in a given network at all times, and it’s most commonly used as the Netgear or D-Link default address for local router configuration. It’s also one of IPv4 addresses, and IPv4 is the protocol that is currently used in most networks around the world. But that’s soon going to change, because the use of IPv6, the successor of this protocol, is on the rise because of insufficient number of IPv4 addresses. Ipv6 supports more address combinations and uses hexadecimal instead of binary system.

The meaning of private IP address

Your Internet Service Provider (ISP) has to assign an IP address to your device that it’s unique each time you’re surfing the Web. On the other hand, your router has a private IP address that can be accessed only on private networks, and this address doesn’t have to be unique. Because it’s not a direct access address, no one can access it outside your private network. However, private addresses can’t connect to the Internet on their own; they actually connect to a network that is already connected to the Internet (ISP), and only then gain access to it.

Finding your public and private IP address

Unless you’re having problems with your computer and you need to connect to it from another device, we are pretty sure that there’s no need for you to know your public IP address. If you still need to locate it for any reason, try visiting some of the IP address returning sites such as www.iplocation.net and www.whatismyip.com. To find your private IP address, access Windows Command Prompt, enter ipconfig and wait for a list of your computer’s connections. That’s the one identified as IPv4 address which anyone in your network can use to contact you.

Changing router’s IP address

Unless you’re having issues with your router, we have to emphasize that it’s probably for the best if you don’t try to change its IP address, because each router comes with defined factory default settings. There can be several connection errors that can be caused by improper address change. For example, If you change your router’s address into one that’s already been taken by another device on the network, you probably won’t be able to access the Internet, or you might experience other connection problems. If you still need to access your router configuration panel and change the address, you can simply enter in your browser address bar. Just keep in mind that only one device on the network should use this address to avoid connection conflicts with other devices.
