What is IP address? | IPV4 & IPV6 | IP address Class

what is IP address | diffrect versions of an IP address  like IPV4 and IPV6 | we learn about what is IP adddress and IP adddress classes. 

What is ip address

what is an IP address :   Your computers in Internet communicate with each other with under ground or underwater cables or wirelessly if want to download a file from Internet then my computers hould have an addresss other computer Internet can find and locate my computer in internet terms that address of computer is called IP address.

 which is identified by your are a postman and you get all the things delivered in this address similarly this is your computer address which is identified by the computer Internet and you get all the downloads available at this computer address this address is the IPaddress of your computer IPaddress stands for Internet Protocol address but what does this mean internal protocol that makes Internet work you are able to watch YouTube video because your computer or your smartphone has an IPaddress and YouTube is sending you all the data related to this video to this IPaddress.

Type of IP Address and IPV4 and IPV6

types Internet Protocol version 4 (IPV4)  and Internet Protocol version 6 (IPV6).

 Internet Protocol version 4 consists of 4 numbers separated with the do teach number can range from 0to255 in decimal numbers.

 but computers do not understand these decimal numbers.

so these numbers are converted to binary form which is computer under standable.

there for in binary this range can be written as 00000000 to 11111111.

 since each numberni srepresented by a group of 8 binary digits.

so the whole ipv4 address is represented by as equence of 32 one sand zeros or simply Is hould say by a sequence of 32 bits so ipv4 is a 32 bits.

INTERNET PROTOCOL VERSION 6, OR IPV6, is that the LATEST VERSION OF the web PROTOCOL, the most COMMUNICATIONS METHOD THAT IDENTIFIES
AND LOCATES COMPUTERS AND OTHER DEVICES ON the web .

WHEN the sooner VERSION WAS DEVELOPED, it had been referred to as IPV4, AND HAD the power TO SUPPORT 4.3 BILLION DEVICES.

BACK within the 1990S, PEOPLE THOUGHT that might BE ENOUGH.

BUT THEY WERE WRONG! because of the expansion of private COMPUTERS,
SMARTPHONES, AND NOW INTERNET OF THINGS DEVICES

LIKE SMART SPEAKERS, SECURITY CAMERAS AND SMART WATCHES, PEOPLE QUICKLY REALIZED THAT THERE WEREN’T getting to BE ENOUGH ADDRESSES
TO GO AROUND.

THE INTERNET ENGINEERING TASK FORCE, OR IETF, CREATED IPV6, WHICH USES 128-BIT ADDRESSING TO SUPPORT 340 TRILLION TRILLION TRILLION ADDRESSES.

INSTEAD OF FOUR SETS OF 1 to three
DIGIT NUMBERS, IPV6 USES EIGHT GROUPS of 4 HEXADECIMAL DIGITS, SEPARATED BY COLONS.

IPV6 ALSO PROVIDES MORE EFFICIENT PACKET HANDLING, IMPROVING PERFORMANCE AND SECURITY.

YET DESPITE THIS, the remainder OF the web IS TAKING ITS SWEET TIME TO TRANSITION FROM IPV4 TO IPV6.

 MOST COUNTRIES OFFICIALLY “SOLD OUT”
OF IPV4 ADDRESSES, MORE COMPANIES AND GROUPS ARE LIKELY to modify OVER TO IPV6.

SWITCH’ DATE - THERE’S NOTHING SCHEDULED WHERE IPV4 is not any LONGER SUPPORTED.

AS MORE COMPANIES AND ISPs UPGRADE THEIR EQUIPMENT TO IPV6, the planet WILL SLOWLY MOVE faraway from .

IP Address Classes 

TCP/IP defines five classes of IP addresses: class A, B, C, D, and E. Each class features a range of valid IP addresses. the worth of the primary octet determines the category . IP addresses from the primary three classes (A, B and C) are often used for host addresses. the opposite two classes are used for other purposes – class D for multicast and sophistication E for experimental purposes.

The system of IP address classes was developed for the aim of Internet IP addresses assignment. The classes created were supported the network size. for instance , for the tiny number of networks with a really sizable amount of hosts, the category A was created. the category C was created for varied networks with small number of hosts.

Class	Address range	Supports
Class A	1.0.0.1 to 126.255.255.254	Supports 16 million hosts on each of 127 networks.
Class B	128.1.0.1 to 191.255.255.254	Supports 65,000 hosts on each of 16,000 networks.
Class C	192.0.1.1 to 223.255.254.254	Supports 254 hosts on each of 2 million networks.
Class D	224.0.0.0 to 239.255.255.255	Reserved for multicast groups.
Class E	240.0.0.0 to 254.255.255.254	Reserved for future use, or research and development purposes.

For the IP addresses from Class A, the primary 8 bits (the first decimal number) represent the network part, while the remaining 24 bits represent the host part. for sophistication B, the first 16 bits (the first two numbers) represent the network part, while the remaining 16 bits represent the host part. for sophistication C, the primary 24 bits represent the network part, while the remaining 8 bits represent the host part.

Consider the subsequent IP addresses:

10.50.120.7 – because this is often a category A address, the primary number (10) represents the network part, while the rest of the address represents the host part (50.120.7).


172.16.55.13 – because this is often a category B address, the primary two numbers (172.16) represent the network part, while the rest of the address represents the host part (55.13). a tool with the IP address of 172.16.254.3 is on an equivalent network, while a tool with the IP address of 172.55.54.74 isn’t.
