IP addresses provide a method to uniquely identify every system connected to a network. Public IP addresses are routable over the Internet while private IP addresses may only be used on local area networks. In this video, learn how IP addresses are assigned and managed.
- For the internet protocol to successfully deliver traffic…between any two systems on a network,…it must have an addressing scheme.…Just like telephones use phone numbers…and postal mail uses street addresses,…the internet needs an addressing scheme.…Because the addresses are used by the internet protocol,…they are known as IP addresses.…In most cases, IP addresses are written in what's known as…the dotted quad notation.…This means that they are four numbers separated by periods.…
Each number may range between 0 and 255.…Why 255?…Because each number is represented using 8 binary bits,…and those bits can represent two to the eighth power…possible numbers,…two to the eighth is 256,…but since we start counting at 0 we can only go up to 255…in our IP address values.…A system's IP address uniquely identifies it on a network.…If the system is directly connected to the internet,…the IP address it uses must not be used…by any other system in the world.…
Just as your mobile phone number…is not used elsewhere in the world.…
