What does each octet in an IP address represent?

Each of the four octets of an IP address represents either the network portion or the host portion of the address, depending on the address class. The network and host portions of the respective Class A, B, C, and D addresses are shown in Figure 2-2.

How many octets does an IP have?

4 octets
An IP address is, as such, generally shown as 4 octets of numbers from 0-255 represented in decimal form instead of binary form.

What is the last octet in a IP address?

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 does the 3rd octet mean?

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 3rd octet of an IP address mean?

As stated above, a Class A address has the first octet as the network portion and the remaining 3 octets as the host portion. Therefore, a Class A network mask is defined as 255.0. 0.0. A Class B address has the first and second octets as the network portion and the third and fourth octets as the host portion.

How many octets are there?

The octet is a unit of digital information in computing and telecommunications that consists of eight bits….Octet (computing)

octet
Unit system	units derived from bit
Unit of	digital information, data size
Symbol	o
In primary units of information	1 o = 8 bits

How many octets make up an IPv4 address?

four octets
An IPv4 address must contain three periods and four octets. The following examples are valid IPv4 addresses: 1 .

Which octet of the subnet mask 255.255 255.0 will tell?

Class C networks use a default subnet mask of 255.255. 255.0 and have 192-223 as their first octet.

What are the first 3 octets of an IP address?

The first 24 bits (the first three octets) identify the network and the remaining 8 bits indicate the host within the network. An example of a Class C IP address is 200.168. 212.226 where “200.168. 212” identifies the network and “226” identifies the host on that network.

What is the 4th octet of IP address?

Octet 4 (the last 8 bits) is for hosts. Class C addresses are used for networks with less than 254 hosts.
