History Of IP (Internet Protocol) Address
Internet Protocol (IP)
This is a fundamental protocol to communicate between network devices. It is set the way of information is packetized, routed, transferred, addressed, and received by networked devices.
The History Of IP (Internet Protocol)
The IP born in the year 1974, the founder of IP is computer scientists Bob Kahn and Vint Cerf. Its also called TCP/IP because it used in conjunction with the TCP or you can call Transmission Control Protocol.
The most used or 1st major IP version is version 4, or you can call it IPv4. In the year 1981, is defined in RFC 791 by IETF (Internet Engineering Task Force).
In this year (2019) a new version of IP IPv6 that was formalized by IETF in 1998 is governed approx 20% of all Internet Traffic.

Internet Protocol Address
This is similar like an E-mail or Mail service, mail addresses identify the locations where the mail goes and come from. The IP address also identifies where the packets go and come in the network.
What is IPv4
An example of IPv4 address is “18.104.22.168“, IPv4 address is 32 bits or 4 bytes long. 232 or 4,294,967,296 is the maximum value of an IPv4 IP address. This is called its “address space“ and it is about 4.3 billion. In the earlier time (1980) this was sufficient for addressing every network device, but it’s all known that near future it won’t be sufficient. Scientists may bring technology like NAT (it allows many devices in a single IP) to delay the situation, but we all know a larger “address space“ is needed to save the future internet service. So scientists introduce the latest version of IP “IPv6“.
What is IPv6
IPv6 is made for larger address space, it comes with 128 bits of data storage in an address. That permit 340,282,366,920,938,463,463,374,607,431,768,211,456 or 2128 unique addresses. All it produces 340 duodecillion large number of address space.
Classes Of IP
IP address divided into 5 classes, they are Class A, Class B, Class C, Class D, and Class E. For detailed you can read our “What Is My IP Address“ post.
Breakdown Of IP Address
IPv4 is broken down into 4 octets or bytes and translated into the binary that represents the actual IP address. Here is an example.
Lets take 255.255.255.255 as IPv4 address.
Into Decimal- 255.255.255.255
Into Binary- 11111111.11111111.11111111.11111111
Into Hexadecimal- FF.FF.FF.FF
Into Octal- 377.377.377.377
Lets take another example of IPv4 breakdown, in this example take 22.214.171.124 is the IP address.
Decimal Value: | 166 | 70 | 10 | 23 |
Binary Value: | 10100110 | 01000110 | 00001010 | 00010111 |
Conversion: | 128+32+4+2=166 | 64+4+2=70 | 8+2=10 | 16+4+2+1 =23 |
Dynamic IP vs Static IP Address
There are two options to assigned IP address one is dynamic another one is static.
The most home network is DHCP configured mean its dynamically assigned IP addresses (to know more about DHCP click here). Mostly your home router assigns an IP address that stays on the lease time, after the lease time end it will automatically renew with a unique IP address and the circle continues.
In static IP address, it assigned manually and it stays same if you don’t change, Most workstations use static IP addresses.
How IP Addresses Works On Network
End User Device (Your Computer)
Your device connects to your network router using TCP/IP and asks for a local IP address. If you don’t have DHCP network then you have to set an IP address manually.
The router assigned a local IP address for your device.
Your router requests an IP address or if you have static WAN IP then request to verify it to ISP. After the process completes your network’s Internet connection is turned on.
When you want to access a web service, you put the address on the address bar and hit enter it will translate (using DNS) to an IP address behind the name server (“digitechind.in“ is name server, “126.96.36.199“ in the IP address) and the TCP/IP packet travels into multiple network devices and computers until it reaches final destination.
End User Device (Your Computer)
After reaches the final destination it will respond back to your device. And the whole system repeats again and again.
