What are the first 2 octets of an IP address?

The first two octets ( 16 bits) identifies a network administered by the Comcast (an Internet Service Provider). The last two octets (the final 16 bits) identifies a home computer on that Comcast network. An illustration of the IP address space. Multiple networks are shown with different 2-octet strings above them.

What is the first octet of an IP address?

Class A addresses
Class A addresses were intended to accommodate very large networks, so only the first octet is used to represent the network number. This leaves three octets, or 24 bits, to represent the host portion of the address. With 24 bits total, 224 combinations are possible, yielding 16,777,216 possible addresses.

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 are the two parts of an IP address?

The bytes of the IP address are further classified into two parts: the network part and the host part.

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 octet in IP address?

Octets or segments, or a combination of both, make up Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) addresses. x where x is called an octet and must be a decimal value between 0 and 255. Octets are separated by periods. An IPv4 address must contain three periods and four octets.

What do the octets in an IP address mean?

Each of the decimal numbers in an IP address is called an octet. The term octet is just a vendor-neutral term instead of byte. So, for an IP address of 168.1. 1.1, the first octet is 168, the second octet is 1, and so on. The range of decimal numbers numbers in each octet is between 0 and 255, inclusive.

How many bits is octet in IP?

The 32-bit IP address is grouped 8 bits at a time, each group of 8 bits is an octet. Each of the four octets are separated by a dot, and represented in decimal format, this is known as dotted decimal notation.

What do the parts of an IP address mean?

An IP address consists of two parts, one identifying the network and one identifying the node, or host. The Class of the address determines which part belongs to the network address and which part belongs to the node address. All nodes on a given network share the same network prefix but must have a unique host number.

What are the parts of IP address and define each part?

Every IP address—such as 76.240. 249.145—is also divided into two sections that define 1) your network and 2) your computer, or host. Those two sections comprise the basic structure of IP addresses: the network ID and the host ID. Each computer (sometimes called a “network interface”) has its own unique host ID.

What are the 4 parts of an IP address?

An IPv4 address is composed of four sets of 8 binary bits, which are called octets. The result is that IP addresses contain 32 bits. Each bit in each octet is assigned a decimal value. 32, 16, 8, 4, 2, and 1, left to right.

What is typical IP address format?

The Format of an IP Address. The format of an IP address is a 32-bit numeric address written as four numbers separated by periods. Each number can be zero to 255. For example, 1.160.10.240 could be an IP address.

What is the breakdown of an IP address?

The breakdown. Your IP address and everyone else’s is made up of four fields of numbers separated by three dots. (Go to the WhatIsMyIPAddress home page to see yours right now.) You can read each field as its own number, which can range from 0 to 255. An IP address could be 66.171.248.172, for example.

What is an IP address structure?

The IP address structure is similar to the mail system architecture. There is a specific part in the IP header that identifies the country part of the address. A separate field identifies the postal code and street name within the country and another one identifies the actual mail box and name of a particular host.
