An IP address uniquely identifies a device or network on the Internet. Additionally, geographical information about the location of an IP address is provided below. This is known as IP geolocation. To retrieve geolocation data on an IP, enter it in the textbox provided and click Look Up. Try 188.8.131.52 which is one of Google's public DNS IP addresses. It is important to keep in mind that IP geolocation is not as accurate as other methods of geolocation, such as GPS.
IP - An IP (Internet Protocol) address is a unique identifier used in network communication. Network devices, such as a computer, a network printers and a router, all have a unique IP within their own network to enable you to print your document to your network, connect to a website, or play online games. An IP address is analogous to a phone number.
These special addresses are IPs that are reserved for network testing and troubleshooting and are not assigned to devices.
The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of IP address space for private networks. These private IP addresses are typically used in local networks and cannot be accessed directly from a public network such as the Internet.
