How To Use IPv6 In Enterprise Networks
NetWORK, Monday, May 13th, 2024
The transition to IPv6 is a learning curve. Here's what to understand about IPv6, including benefits, troubleshooting techniques and best practices for secure integration.
IPv4 has been the standard logical addressing protocol for decades. IPv4 is important to internet history as it enabled capabilities like client-server networking, cloud computing, web e-commerce and more.
But IPv4 isn't without its weaknesses, and newer innovations have exceeded its capabilities. Challenges of IPv4 include the following:
- Limited number of available addresses -- approximately 4.3 billion.
- No built-in encryption for confidentiality, integrity or authenticity.
- Extensive and unorganized worldwide routing capabilities.
Most enterprises are aware of IPv6, the latest generation of IP, which also serves as IPv4's replacement. IPv6 overcomes IPv4's limitations and offers a new approach to networking. IPv6 provides more address spaces, integrated encryption via IPsec and more efficient routing, among other enhanced features.
