What is an IP address? Why is it important?

An IP address is a unique identification code used to assign a device and shares the location and address of the device with the IP address. The IP address has been used for decades now with the first being created in 1980 in IPv4 and was defined in RFC 760. IPv4 has been the traditional one with 32-bit addresses and limited to a very small amount of actual addresses that have been assigned hence, a change and an upgrade were required which resulted in the birth of IPv6 which stores 128-bit addresses. These are assigned to various amount of devices which include computers, mobile devices, IP phones, servers, websites, or anything that is connected to the vast network of the internet.

IP addresses are given according to various servers and the number of devices that are connected to them, there can be dynamic or static ones. IP addresses can not be replicated, which means if the server overloads some of the devices get kicked out, resulting in a crash screen as the server tries to make room for the device that is trying to connect the latest. Hence, you may sometimes get disconnected or timed out when accessing a website that has a low traffic capacity.

IP address management

As we discussed above how IP addresses are located dynamically as well as statically. Manually allocating a device with an IP address on a subnet can be considered the static form of assigning an IP address. Whereas one can use a DHCP server that assigns an IP address that is stored dynamically as a device joins in on the network. Generally, IP addresses can be masked by using a VPN service but if not, one can track down the location and the information regarding the PC that holds that certain IP address. When a PC leaves the server the DHCP server then has that void for other devices to connect to that IP address and the process just goes on and on as the cycle continues.
