What are the 4 octets of an IP address?
What are the 4 octets of an IP address?
An IP address is an address used in order to uniquely identify a device on an IP network. The address is made up of 32 binary bits, which can be divisible into a network portion and host portion with the help of a subnet mask. The 32 binary bits are broken into four octets (1 octet = 8 bits).
What do the octets in an IP address mean?
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 are octets chemistry?
Octet, in chemistry, the eight-electron arrangement in the outer electron shell of the noble-gas atoms. This structure is held responsible for the relative inertness of the noble gases and the chemical behaviour of certain other elements.
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 an octet equal to?
An octet is unit of digital information equal to exactly eight bits.
Can an IP address have 3 octets?
IP Address Classes: IP addressing supports three different commercial address classes; Class A, Class B, and Class C. Octets 3 and 4 (the next 16 bits) are for the hosts. Class B addresses are used for networks that have between 256 and 65,536 hosts. In a class C address, the first three octets are the network portion.
How many octets are there in 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.
How is an octet represented in a binary format?
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).
Why is the octet rule applicable to the main group elements?
It is based on the observation that the atoms of the main group elements have a tendency to participate in chemical bonding in such a way that each atom of the resulting molecule has eight electrons in the valence shell. The octet rule is only applicable to the main group elements.
How many bits are in an IP address?
IP Addressing Basics IP version 4 (IPv4) addresses, which uniquely identify a device on an IP network, are 32 bits in length and are typically communicated in a format known as dotted decimal. The 32 binary bits are: • Divided into a network portion and host portion • Broken into four octets (1 octet = 8 bits).
