Internet Protocol


The Internet Protocol (IP) is a set of rules that governs the transmission of data over the internet or any other network. It basically involves the packaging of data into packets and their transportation from the source to the destination based on the IP addresses. This protocol is the primary mechanism that makes up the foundation of the internet and enables inter-network communications.


The phonetics of the keyword “Internet Protocol” is: Internet: /ˈɪntərˌnɛt/Protocol: /ˈproʊtəˌkɔl/ or /ˈproʊtəˌkɒl/

Key Takeaways

Three Main Takeaways About Internet Protocol

  1. Function: Internet Protocol (IP) is responsible for addressing and routing of packets of data on the internet. It handles the task of delivering packets from the source host to the destination host solely based on the IP addresses in the packet headers.
  2. Types: There are two main versions of Internet Protocol in use today: IPv4 and IPv6. IPv4 – uses 32 bits for its Internet addresses and it can support 2^32 (over 4 billion) IP addresses. IPv6 – uses 128 bits for its Internet addresses and can support vastly more addresses.
  3. Relationship with TCP: IP goes hand-in-hand with the Transmission Control Protocol (TCP) to deliver data over the internet. While IP ensures the information gets from one point to the other, TCP ensures the data is correctly unpacked at the other end.


The technology term Internet Protocol (IP) is critically important as it is fundamentally responsible for the transmission of data across network boundaries. It is primarily tasked with defining, structuring, and delivering information packets from point A to point B. IP is among the core protocols that facilitate internet connectivity, allowing computers to communicate with one another through a shared network. Every device connected to the internet has a unique IP address, which helps in identifying the sender and recipient of information. As such, the Internet Protocol not only acts as a vital identifier but also as a navigation mechanism, enabling a vast array of internet-based technological functions and systems, making it a cornerstone of the World Wide Web.


Internet Protocol, commonly known as IP, plays a central role in modern internet-based communication by conveying information across networks and devices globally. Its primary purpose is to identify and locate devices on the network, enabling accurate routing and delivery of data packets. Just like a postal system that relies on precise addresses to deliver mail, IP ensures all pieces of data, which are broken down into packets for transmission, reach their correct destination. Each device on the Internet, be it a personal computer, a mobile phone, or a server, has a unique IP address, which helps Internet Protocol route packets from the source to the target device.In addition to delivery, the Internet Protocol also facilitates reliable communication through functions like packet fragmentation and reassembly. If a data packet is too large for transmission over the network, IP splits it into smaller fragments that are sent separately and reassembled at the destination. This packet-switching capability ensures the efficient use of available bandwidth while maintaining the integrity of the data transmitted. Similarly, ICMP, a supporting protocol, assists IP by delivering error messages and operational information indicating, for example, when part of the network is congested or a specific device cannot be reached. Thus, Internet Protocol is a fundamental building block in ensuring seamless, undisturbed, and efficient data exchange over the internet.


1. Email: Email services like Gmail, Outlook or Yahoo are based on Internet Protocol (IP). When you send an email, your message is broken down into packets of data that include your IP address and the recipient’s. As the packets move through the Internet, different routers read the IP addresses to direct them to their proper destination.2. Video Streaming: When you watch a movie on platforms like Netflix or YouTube, the video is broken down into data packets and transported over the internet using Internet Protocol. Each packet includes IP addresses that determine where the packet came from and where it is going, ensuring the video plays smoothly on your device.3. Voice over Internet Protocol (VoIP): Services like Skype, WhatsApp, and Zoom use VoIP technology for delivering voice communications and multimedia sessions over the Internet. Your voice is converted into digital data, encapsulated in IP packets, and transmitted over the internet to the receiver. This process is reversed on the other end to convert the digital data back into audible sound.

Frequently Asked Questions(FAQ)

Q: What is Internet Protocol (IP)?A: Internet Protocol is a set of rules that facilitate sending and receiving data over the internet. It identifies and locates computers on a network by assigning unique numerical addresses to them.Q: What are the different versions of the Internet Protocol?A: The two versions of the IP are IPv4 and IPv6. IPv4 uses 32-bit addresses while IPv6 utilizes 128-bit addresses, allowing for a greater number of unique addresses.Q: What is the difference between TCP/IP and IP?A: IP is a protocol used for communicating data across a packet-switched network. TCP (Transmission Control Protocol) is another protocol that is built on top of IP to ensure data is reliably delivered.Q: What is an IP address?A: An IP address is a unique number assigned to every device connected to the internet, allowing those devices to communicate with each other. It serves two primary functions – host identification and location addressing.Q: What is the difference between a static IP address and a dynamic IP address?A: A static IP address is a fixed address assigned to a device. It doesn’t change unless manually altered. On the other hand, a dynamic IP address is assigned by the network when your device connects and can change over time.Q: Why do we need Internet Protocol?A: Internet Protocol is necessary to send and receive data across the internet. It enables computers to identify each other in a vast network, ensuring that the correct data reaches the intended device.Q: Is it possible to track a device using its IP address?A: Yes, it is possible to track the general geographic location of a device using its IP address. However, it does not usually provide exact locations and can be designed to be hidden or changed through VPNs.Q: How do I find my device’s IP address?A: The process differs based on the operating system. On Windows, one can view it by using the ‘ipconfig’ command in the command prompt. On Mac, you can see it under Network Settings.
