Being connected to the Internet means using an IP or Internet Protocol address. If the concept of IP is clear, the networking work can be done by yourself. The most commonly used IP addresses are those of IP version 4 (IPv-4), which contains a total of 32 bits of data. 1 bit is a number or digit whose value is 1 or 0. One byte with eight bits, it is also called octet. Dividing 32 bits into four (6x4 = 32) gives one octet in each part.

The IP address is separated by an octet dot (.). E.g .: 192.168.100.1. In terms of structure, it again has two parts. Network part and host part. There are five IP addresses in terms of class. Class A (1-126, first octet network part, remaining three hosts), Class B (128-191, first two octet network part, remaining two hosts), Class C (192-223, first three octet network part, left A host). Class D and E are reserved for multicast and scientific research. The middle 127.0.0.1 address is the loopback test, which is the local host address for each user.

Another address is 169.254.0.0 to 169.254.255.255. This is Automatic Private IP Addressing (APIPA). Its function is that if multiple hosts are connected to each other and no IP is placed on the network card, any one of these IPs will automatically sit there and move under the same network. By looking at the numbers used in the first octet, one has to understand which one belongs to which class. In practical terms, classes A, B and C are again divided into two parts — public IP and private IP. Public IPs are used for the Internet and can be routed. And private IPs are specific
