Short Review on IP Networking Basics

Abstract

An IP address is a one-of-a-kind identifier for a device on the internet or within a local network. The term "Internet Protocol" refers to a set of rules that govern how data is transferred over the internet. Following the completion of IPv4 address allocations from IANA and the Regional Internet Registries (RIRs), service providers around the world are wondering how they will continue to provide IPv4 connectivity to their subscribers when there are no longer enough IPv4 addresses to allocate one per subscriber. Several potential solutions to this problem are presently developing, all of which are based on the concept of shared IPv4 addressing. These solutions present a number of challenges, which this memo describes as being common to all address-sharing methods. Application failures, increased service monitoring complexity, new security vulnerabilities, and so on are examples of such difficulties. Discussions on specific solutions are not covered.

Several websites will display the same information: they will be able to see your public IP address because your router submitted a request and so released the information by visiting the site. IP Location takes it a step further by displaying your ISP's name as well as your location. In most cases, this method will only provide an approximation of position – where the provider is, but not the exact location of the device. Remember to log out of your VPN as well if you are doing so. A search warrant must normally be requested to the ISP in order to obtain the real physical location address for the public IP address.
