We need to go deeper lan3/7/2023 Today, the most widely used IP version is IPv4, but the newer version IPv6 is increasingly more popular since it offers a much wider range of unique addresses thanks to its format. Thanks to DNS no one needs to type a series of numbers into the url and just type the name of the desired page. ![]() To make things easier, when users access web services, IP addresses are translated to domain names by DNS servers. An IP address is a unique differentiator that we can imagine as a physical street address. It comprises four 8-digit binary numbers (0,1), for simplification presented in a decimal range of 0-255 separated by periods (example 192.168.2.1). What Is an IP address?Īn IP (Internet Protocol) address is a numerical identifier assigned to devices communicating on a computer network (LAN, WAN, Internet). The decision lies on the administration to choose whether a particular device needs a dynamic or static IP.īut before we dig deeper into what affects the usage of static and dynamic IP, let's explain what IP address is first. Network Address Translation (NAT) solves this problem on the gateway (router) by ensuring the device is provided with a public IP address. Therefore in the case of connecting to the global Internet, a public IP address has to be used. A device has to use a unique identifier to communicate on a network. The local address is unique only in the specific location, but the same range is used in different LANs. These addresses are selected from a pool of internal IP addresses reserved for the internal LAN and thus invisible to the outside world. ![]() In a local network (LAN), devices inside this specific location are assigned a unique IP address manually or automatically by the DHCP server. This article looks at the difference between static and dynamic IP addresses and how to use them. Every internet-enabled device has an IP address so that “IPs” play a crucial role in the interconnected world. The Internet Protocol (IP) enables communication over computer networks, a set of addressing and routing standards that ensure different devices can talk.
