What are the Key Differences Between Protocol Version 2 vs. 1?

The two major versions of the internet protocol (IP) used today in the world wide web are protocol version 1 (IPv1) and protocol version 2 (IPv2). Both protocols concern the ordering and delivery of information over a network. However, there are some significant differences between the two. In this document, we will discuss the major differences between the various versions of the internet protocol, as well as provide advice to developers in understanding which version should be used for their applications.

IPv1 vs. IPv2

Key Differences Between IPv1 and IPv2

Transmission Protocol: IPv1 uses the Transmission Control Protocol (TCP) to establish a connection between two computers, whereas IPv2 uses the User Datagram Protocol (UDP) for this purpose.

Data Fragmentation: IPv1 allows for data to broken up into fragments so that it can be sent more efficiently, whereas IPv2 does not support fragmentation as part of the protocol.

Routing: IPv1 restricts the types of routers that can be used to forward data, while IPv2 is designed to use any type of router infrastructure.

Advantages of IPv2

Network scalability: IPv2 supports a wider range of routing patterns and devices, enabling improved scalability when it comes to complex network deployments.

Efficiency: IPv2 is designed to eliminate the need for a three-step handshake to initiate connections, thus reducing the amount of time needed to move data on the network.

Security: IPv2 has built-in authentications and encryptions for transfer data, making it more secure than IPv1.

Disadvantages of IPv2

Lack of backwards compatibility: IPv2 is not compatible with older devices or operating systems, so devices running earlier versions may not be able to access information sent via IPv2.

Slower speeds: While IPv2 is faster than IPv1 in general, it can suffer from slower speeds when compared to its predecessor in some circumstances.

Complexity: IPv2 is more complex than its predecessor due to its larger number of header fields and variable header lengths. This can cause difficulty for developers in understanding how to properly configure and make use of the protocol.
