What is Internet Protocol (IP)

IP or Internet Protocol is a set of rules for Computers (hosts) to communicate over a system on the internet. Data travels from one system to another on the internet in the form of small packets. Each packet is attached with IP information so that it can reach the correct destination.

IP is a special set of protocols through which communication between the hosts is possible on the internet. One of the basic protocols that is run under the IP is Transmission Control Protocol (TCP). You might also be familiar it with as TCP/IP.

You might also be surprised to know, that TCP is not the only protocol that is part of the IP. Here is the list of Internet Protocols.

  • TCP/IP(Transmission Control Protocol/ Internet Protocol)
  • SMTP(Simple Mail Transfer Protocol)
  • PPP(Point-to-Point Protocol)
  • FTP (File Transfer Protocol)
  • SFTP(Secure File Transfer Protocol)
  • HTTP(Hyper Text Transfer Protocol)
  • HTTPS(HyperText Transfer Protocol Secure)
  • TELNET(Terminal Network)

Versions of Internet Protocol

There are as of now two variants of Internet Protocol (IP): IPv4 and another rendition called IPv6. IPv6 is a developmental move up to the Internet Protocol. IPv6 will coincide with the more established IPv4 for quite a while.


IPv4 (Internet Protocol Version 4) is the fourth modification of the Internet Protocol (IP) used to recognize gadgets on a system through tending to the framework.

The Internet Protocol is intended for use in interconnected frameworks of parcel-exchanged PC correspondence systems. IPv4 is the most generally conveyed Internet convention used to associate gadgets with the Internet. IPv4 utilizes a 32-bit address conspire taking into consideration a sum of 2^32 locations (a little more than 4 billion locations).

With the development of the Internet, it is normal that the quantity of unused IPv4 locations will in the long run out on the grounds that each gadget including PCs, cell phones, and amusement supports associated with the Internet requires an address.

Another Internet tending to framework Internet Protocol form 6 (IPv6) is being sent to satisfy the requirement for more Internet locations.

IPv6 (Internet Protocol Version 6) is additionally called IPng and it is the freshest adaptation of the Internet Protocol (IP) audited in the IETF benchmarks boards of trustees to supplant the present variant of IPv4 (Internet Protocol Version 4).

IPv6 is the successor to Internet Protocol Version 4 (IPv4). It was composed as a developmental move up to the Internet Protocol and will, truth be told, exist together with the more established IPv4 for quite a while.

IPv6 is intended to permit the Internet to become relentless, both as far as the number of hosts associated and the aggregate sum of information movement transmitted. IPv6 is frequently referred to as the “next generation” Internet standard and has been being worked on since the mid-1990s. IPv6 was resulting from worry that the interest for IP locations would surpass the accessible supply.

Difference Between IPv4 vs IPv6

The Internet Protocol Rendition 4 (IPv4) is a convention for use on parcel exchanged Link Layer systems (e.g. Ethernet). IPv4 has a tending capacity of around 4.3 billion locations.

The Internet Protocol form 6 (IPv6) is more exceptional and has better elements than IPv4. It has the capacity to give an unending number of locations. It is supplanting IPv4 to suit the developing number of systems worldwide and take care of the IP address fatigue issue.

One of the contrasts between IPv4 and IPv6 is the presence of the IP addresses. IPv4 utilizes four 1-byte decimal numbers, isolated by a speck (i.e., while IPv6 utilizes hexadecimal numbers that are isolated by colons

Why Switch to IPv6

IPv6 has many benefits over IPv4. Some of them are as follows.

  • IPv6 simplified the router’s task compared to IPv4.
  • IPv6 is more compatible with mobile networks than IPv4.
  • IPv6 allows for bigger payloads than what is allowed in IPv4.
  • IPv6 is used by less than 1% of the networks, while IPv4 is still in use by the remaining 99%.

Technological advancement has turned into the way to business accomplishment in the 21st century. From versatile applications to nontraditional processing gadgets populating the Internet of Things, organizations depend on IT capacity to convey new administrations to both end clients and clients.

Be that as it may, these administrations and the foundation used to bolster them require IP addresses – and that implies an IPv6 relocation. Those associations that pick not to move to IPv6 chance to develop their capacity to advance and drive business development.

On the off chance that since you need to isn’t reason enough to move to IPv6, there are a lot of advantages that ought to make you need to. Most importantly, by diminishing the measure of steering tables, IPv6 makes directing more productive and progressive.

ISPs can total the prefixes of their client’s systems into a solitary prefix that they can declare to the IPv6 Internet. Also, dissimilar to an IPv4 arrangement in which fracture is taken care of by the switch, source gadgets handle discontinuity in an IPv6 organization. Source gadgets are likewise in charge of finding the ways most extreme transmission unit

Since IP-level checksum is excluded in IPv6, the new Internet Protocol can deal with bundles all the more effectively and convey better execution. IPv4 contains an IP-level checksum, so the checksum is computed at each switch jump.

Be that as it may, with most connection layer advances as of now containing checksum and mistake control abilities, and most transport layers having a checksum that empowers blunder identification, it’s not required in IPv6. Presently the time switches already spent checking parcel respectability can be utilized to move information.

To conclude, modern-day technology has forced companies and organizations to change their processes and systems continuously. Without them doing so you risk being left behind and face huge losses.

The ipv6 has numerous benefits over its predecessor and should be the first choice for almost all organizations. Its better performance, effectiveness, and efficiency make it a better version than any before and help realize the company’s goals and objectives.

Companies should evaluate which internet protocol to use and then make decisions accordingly. Currently, there are many organizations leading toward IPV6 due to its superior performance and have every reason to do so and finally settle the debate of IPv4 vs IPv6.
