Definition of IP
An IP address is an abbreviation for the Internet Protocol (in English: Internet Protocol), which is an address used for computing devices, such as: personal computers, tablets, and smart phones. Its mission is to specify an address for the aforementioned devices, so that they can communicate with other devices in the IP network, and it carries all The IP address device is different from other devices, and to zoom in, it is possible to say that it is similar to a street address or phone number. It is used to distinguish the device from other devices.
How IP works
Computing devices use DNS servers, which is an abbreviation for Domain Name System, to look up the hostname and then obtain its IP address. For example, when we access a website, such as: www.q8castle.com through the browser; The login request to load that page goes to the DNS servers, which search for the hostname: q8castle.com, to find its IP address.
IP types
There are two types of IP addresses, the first is the fourth type, known as (IPv4), and the second is the sixth version, known as (IPv6). All computers that have IP addresses contain the first type, and many of them have recently begun using the second type, and to talk about each of them. As follows:
- IPv4 processors: 32 bits are used in the binary system to create one distinct address on the network. The IPv4 address is expressed in four numbers separated by dots, such as: 216.27.61.137
- IPv6 processors: 128 bits are used in the binary system, to create one distinct address on the network, and it is expressed in eight groups of numbers separated by two colons, such as: 2001:cdba:0000:0000:0000:0000:3257:9652, and groups of numbers that contain Zeros to save space, and add a colon in its place, so that the IP in the previous example becomes: 2001:cdba::3257:9652
