Advantages and disadvantages of IPV4

The Internet Protocol Version 4 (IPV4) is the first version of the protocol (IP). In 1983, it was made available for development on the ARPANET. It is currently the most commonly used IP version. It is used in conjunction with an addressing scheme to classify devices on a network. IPV4 is the 32-bit address scheme which is allowing to storage of 2^32 addresses which is more than 4 billion addresses. So here this article gives the advantages and disadvantages of IPV4 to better understand this topic.

Advantages of IPV4:

  • IPV4 is necessary to encrypt data to ensure privacy. It takes security measures to encrypt data in its address packets.
  • IPV6 protocol can be easily supported by most of the topology drawings. 
  • Since addresses are combined more effectively the process of routing has become more efficient in IPV4.
  • Both devices can easily handle IPV4 routing, which is part of the IPV4 protocol. As a consequence, practically every major device will accept the IPV4 protocol.
  •  IPV4 does to great lengths to ensure that data packets arrive at their destination. This is because the transmission control protocol employs IPV4 variants.
  • IPV4's main aim is to connect various types of devices to one another.

Disadvantages of IPV4:

  • By defining the use of the internet, IPsec provides network protection to IPV4. However, the issue arises when IPSec is not built-in and its use is optional.
  • IPV4 needs either manual or automatic configuration. DHCP is difficult because its infrastructure needs different management.
  • Despite the fact that IPV4 has a mobility specification, it is considered inefficient. This is due to the fact that it operates on its own infrastructure. Its mobility nodes are also unsuccessful.
  • Individual IPV4 address prefixes are allocated to each router so that it can operate independently. Today's Internet uses both flat and hierarchical routers. On the internet, there are over 85000 roads.
