[Podcast] The back of the class: Looking at 240/4 reachability
Geoff Huston explores the feasibility and implications of utilizing the 240.0.0.0/4 class-E IP address space for routing purposes.
MAIN POINTS
- Class-E IP addresses, specifically 240.0.0.0/4, are traditionally reserved and not routable.
- The potential use of these addresses could alleviate IPv4 address exhaustion.
- Technical challenges exist in making class-E addresses routable.
- The study examines the impact on existing network infrastructure.
TAKEAWAYS
- Revisiting reserved IP spaces could provide temporary relief for IPv4 scarcity.
- Implementation would require significant changes in network protocols and hardware.
- Understanding the current limitations is crucial for future IP address management.
- Collaboration among network stakeholders is necessary to address technical hurdles.
