What does the first octet in an IP address represent?

What does the first octet in an IP address represent?

The first 8 bits (the first octet) identify the network and the remaining 24 bits indicate the host within the network. 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.

What is the use of IP 127?

Local Loopback Address is used to let a system send a message to itself to make sure that TCP/IP stack is installed correctly on the machine. In IPv4, IP addresses that start with decimal 127 or that has 01111111 in the first octet are loopback addresses(127.

What does each octet mean in an IP address?

An IP address is typically written in decimal digits, formatted as four 8-bit fields separated by periods. Each 8-bit field represents a byte of the IP address. This form of representing the bytes of an IP address is often referred to as the dotted-decimal format.

What is the last octet in a IP address?

host portion
The last octet is the host portion of the IP address. That’s where you’d assign your devices. In this case, you could assign up to 254 hosts. (More on that later.)

What is the 3rd octet of an IP address?

To perform subnetting,the third octet (in this example) is used to identify unique subnets of network 150.150. 0.0. Notice that each subnet number in the figure shows a different value in the third octet, representing each different subnet number.

What does the IP address 0.0 0.0 signify?

A 0.0. 0.0 address indicates the client isn’t connected to a TCP/IP network, and a device may give itself a 0.0. 0.0 address when it is offline.

What does 24 mean in IP address?

2.0/24”, the number “24” refers to how many bits are contained in the network. From this, the number of bits left for address space can be calculated. As all IPv4 networks have 32 bits, and each “section” of the address denoted by the decimal points contains eight bits, “192.0.
