IP Address

As described in the website howstuffworks.com (What is IP Address?), "Assign an IP address to each device connected to the Internet, because it consists of four binary octets, This is a 32 bit protocol, but they are usually written in decimal for ease of use The maximum decimal number permitted for octets is 255 (or 11111111 for binary.) Therefore 4 The total number of unique possibilities for octets is 256 ^ 4, about 3 billion addresses.Demand for IP addresses is increasing for reasons such as low computer cost, advances in technology, and improved accessibility.

You may have heard the IP address before. An IP address, like an actual address, is a unique identifier that each computer has. Internet Protocol (IP) is the most basic level of messaging protocol. Only 20 bytes of data including the target IP address and sender IP address are used. UDP is used for high speed and efficient transmission, but it is not always reliable. It basically sends a lot of packets, it is done. Although TCP takes a little more time, reliability is higher because it confirms the arrival of the actual message. This means that a confirmation message was received at the other end.

Pay particular attention when displaying the number of hosts on the network. The first IP address in the network is the network address, and the last IP address is always the broadcast address. Therefore, IP address 1.1.1.0 and IP address 1.1.1.255 can not be used. These are special reservation addresses, but some computers can use the network address as the actual computer address. "Subnetting" is to divide a single network into smaller networks. To do this, you need to add more bits (more numbers) to the subnet mask. Traditionally, we are used to seeing subnet masks that look like 255.0.0.0, 255.255.0.0, or 255.255.255.0. However, the subnet mask will also be like 255.255.128.0 or 255.255.255.224. In either case it is clear that the network is subnetted to divide one network into smaller networks.

An IP address is an address used to uniquely identify a device on an IP network. The address consists of 32 binary bits that can be divided into a network part and a host part using a subnet mask. The 32 bit binary bit is divided into 4 octets (1 octet = 8 bits). Each octet is converted to a decimal number and is separated by periods (dots). Therefore, IP addresses are said to be represented in dotted decimal format (eg, 172.16.181.100). The value of each octet is a decimal number from 0 to 255, or a binary number from 00000000 to 11111111.
