Why Change IP Address?Īn IP address can sometimes already be linked to your identity. Websites employ the public IP address to prevent spam, track users, and enforce geo-targeting and filtering of content. Your IP address may give information about your location. It’s also worth noting that your public IP address is sent with every online request you make, and websites you visit can see it. You can’t have two devices with the same IP address on the Internet unless they’re utilizing a proxy server. Public IP addresses are unique IP addresses assigned to devices on the Internet by Internet Service Providers (ISPs). Unlike local IP addresses, public IP addresses are exposed to the Internet and, as a result, are not required to be globally unique. Another example is your home network, where your router assigns local IP numbers to all of the devices connected to it to recognize and communicate with them properly. The same IP address could be used in thousands of networks without trouble. Local IP addresses are only required to be globally distinctive within a network. Each of these devices will have its local IP address for connecting to the café server. Consider a LAN network in a small café with PCs, fingerprint scanners, printers, document scanners, and other devices. IP addresses assigned within a network but not exposed to the Internet are local IP addresses. An IP address can be viewed as a postal address, which is where the issue lies: it can be used to uniquely specify a computer or network (in the case of a LAN) and expose its location.

Identification and location addressing are the two most common uses of IP addresses. IP addresses can be 32-bit ( IPv4) or 128-bit numerical labels written in human-readable form. 6.4 Can You Change An IP Address?
