In a Class B Network, binary addresses start with 10, therefore the decimal number can be anywhere from 128 to 191. An example of a Class A IP address is 102.168.212.226, where “102” identifies the network and “168.212.226” identifies the host on that network.
The first 8 bits (the first octet) identify the network and the remaining 24 bits indicate the host within the network. In a Class A Network binary address start with 0, therefore the decimal number can be anywhere from 1 to 126. All nodes on a given network share the same network prefix but must have a unique host number. The Class of the address determines which part belongs to the network address and which part belongs to the node address. To learn more about Network Certification, check out these courses. The Two Parts of an IP AddressĪn IP address consists of two parts, one identifying the network and one identifying the node, or host. However, the binary number is important because that will determine which class of network the IP address belongs to. For example, the IP address: 168.212.226.204 in binary form is 10101000.11010100.11100010.11001100.īut it is easier for us to remember decimals than it is to remember binary numbers, so we use decimals to represent the IP addresses when describing them. Recommended Reading: Learn more about the TCP/IP protocol.Īn IP address consists of 32 bits, often shown as 4 octets of numbers from 0-255 represented in decimal form instead of binary form. Networks using the TCP/IP protocol route messages based on the IP address of the destination. What is an IP Address?Īn IP address is an identifier for a computer or device on a TCP/IP network. Every computer that communicates over the Internet is assigned an IP address that uniquely identifies the device and distinguishes it from other computers on the Internet.Įvery computer that communicates over the Internet is assigned an IP address that uniquely identifies the device and distinguishes it from other computers on the Internet.
