IP addresses are a fundamental component of internet connectivity, with IPv4 having been the standard for many decades. However, due to the depletion of unique IPv4 addresses, transitioning to IPv6 is becoming increasingly important. This post compares IPv4 and IPv6, highlighting the key differences and what they mean for businesses.

What is IPv4?

IPv4, or Internet Protocol version 4, is the fourth iteration of the Internet Protocol, using a 32-bit address scheme that allows for 4.3 billion unique addresses. While initially considered sufficient, the rapid growth of connected devices has quickly exhausted this pool.

  • Structure: IPv4 addresses are written in decimal format, with four sets of numbers separated by periods (e.g., 192.168.1.1).
  • Scarcity: The limited number of available addresses has made IPv4 a scarce resource, leading to increased costs and reliance on solutions like Network Address Translation (NAT) to extend address usability.
  • Usage: Despite its limitations, IPv4 remains widely used due to its compatibility with legacy systems and the established infrastructure that supports it.

What is IPv6?

IPv6, or Internet Protocol version 6, was developed to address the limitations of IPv4, particularly the issue of address exhaustion. It uses a 128-bit address scheme, providing approximately 340 undecillion unique addresses.

  • Structure: IPv6 addresses are written in hexadecimal format, consisting of eight groups of four characters separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).• Abundance: With its vast address space, IPv6 eliminates the need for NAT and allows for simpler network configurations, especially as the number of internet-connected devices continues to grow.
  • Adoption: While IPv6 adoption has been slower than anticipated, it is gradually increasing as businesses recognize the necessity of transitioning to a protocol that can accommodate future growth.

The Transition from IPv4 to IPv6

The transition from IPv4 to IPv6 is driven by the need for more IP addresses in an expanding digital world. While IPv4 addresses are still in use, their limitations are becoming more apparent as the demand for connectivity grows. IPv6, with its vast address space and advanced features, offers a solution to these limitations, but the transition requires careful planning and execution.
Businesses need to prepare for a dual-stack environment where both IPv4 and IPv6 are supported during the transition phase. Ensuring infrastructure, software, and devices are compatible with IPv6 is critical to avoiding connectivity disruptions.
