# How many octets are there in IP address?

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. Each bit in an octet has a binary weight (128, 64, 32, 16, 8, 4, 2, 1).

Correspondingly, what is 1 octet?

Octet is the correct form for 8 bits. Even though we often use byte to represent 8 bits there are systems that use other than 8 bits for a byte. But since everyone uses it to represent 8 bits it could be argued that it is.

What is meant by the octet rule?

The octet rule is a chemical rule of thumb that reflects observation that atoms of main-group elements tend to combine in such a way that each atom has eight electrons in its valence shell, giving it the same electron configuration as a noble gas.

What is an octet in binary?

Tech Stuff – Hexadecimal, Decimal and Binary. The basic unit used in the computer world is the byte (a.k.a octet), a byte (or octet) has 8 bits (a.k.a binary digits). Thus, a memory location with the 12-bit binary value of 000.001.100.111 would be written in octal as 0147.

## What is a private IP address?

A private IP address is a non-Internet facing IP address on an internal network. Private IP addresses are provided by network devices, such as routers, using network address translation (NAT). Private IP addressing uses addresses from the class C range reserved for NAT (192.168.0.0 – 192.168.255.255).

## How many Class B networks are there?

Key Concept: In the “classful” IP addressing scheme, a Class A network contains addresses for about 16 million network interfaces; a Class B about 65,000; and a Class C, 254. As you can see, there is quite a disparity in the number of hosts available for each network in each of these classes.

## How long is the 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. Within an isolated network, you can assign IP addresses at random as long as each one is unique.

## What is a Class D IP address used for?

Class D addresses are 32-bit network addresses, meaning that all the values within the range of 224.0.0.0 – 239.255.255.255 are used to uniquely identify multicast groups. There are no host addresses within the Class D address space, since all the hosts within a group share the group’s IP address for receiver purposes.

## How long is an ipv4 address?

IPv6 addresses are 128 bits (as opposed to 32 bits of IPv4 addresses). They are usually written as 8 groups of 4 hex digits separated by colons: 2001:0db8:85a3:0000:0000:8a2e:0370:7334 . 39 characters is appropriate to store IPv6 addresses in this format.

## How many layers are there in the TCP IP model?

TCP/IP protocols map to a four-layer conceptual model known as the DARPA model , named after the U.S. government agency that initially developed TCP/IP. The four layers of the DARPA model are: Application, Transport, Internet, and Network Interface.

## How many octets does an ipv4 address consist of?

Each octet can have 1-255 value only. IPv4 uses 32 bits so it has 4 octets. IPv6 uses 128 bits, so it has 16 octets. However we express IPv6 addresses as 8 16 bit numbers(hexadecimal notation).

Broadcast is possible also on the underlying Data Link Layer in Ethernet networks. Frames are addressed to reach every computer on a given LAN segment if they are addressed to MAC address FF:FF:FF:FF:FF:FF. Ethernet frames that contain IP broadcast packages are usually sent to this address.

## What is an octet in chemistry?

The octet rule is a chemical rule of thumb that reflects observation that atoms of main-group elements tend to combine in such a way that each atom has eight electrons in its valence shell, giving it the same electron configuration as a noble gas.

## What is the first octet of an IP address?

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. Each bit in an octet has a binary weight (128, 64, 32, 16, 8, 4, 2, 1).

## What is the network address for apipa?

If the client is unable to find the information, it uses APIPA to automatically configure itself with an IP address. The IP address range is 169.254.0.1 through 169.254.255.254. The client also configures itself with a default class B subnet mask of 255.255.0.0.

## What is meant by CIDR?

Classless Inter-Domain Routing

## What is the CIDR notation?

Classless inter-domain routing (CIDR) is a set of Internet protocol (IP) standards that is used to create unique identifiers for networks and individual devices. That system is known as CIDR notation. CIDR IP addresses consist of two groups of numbers, which are also referred to as groups of bits.

## What is the subnet mask for a Class C IP address?

To divide a given network address into two or more subnets, you use subnet masks. The default subnet masks for class A networks is 255.0.0.0, for class B is 255.255.0.0, and for class C is 255.255.255.0, which signify a network without subnets.

## What is 1 octet?

Octet is the correct form for 8 bits. Even though we often use byte to represent 8 bits there are systems that use other than 8 bits for a byte. But since everyone uses it to represent 8 bits it could be argued that it is.

## What is a simple definition of the octet rule?

The Octet rule is a general rule of thumb that applies to most atoms. Basically, it states that every atom wants to have eight valence electrons in its outermost electron shell.
