Episode notes
James Harr's IPv6 Journey
- James Harr initially resisted IPv6 because he thought IPv4 was sufficient and IPv6 seemed complicated.
- After working in a dual-stack environment, he realized IPv6 was not as scary and saw varied adoption levels in different organizations.
Challenges of Dual-Stack Networking
- Running dual-stack means managing two parallel networks, which can be seen as complex or difficult.
- Transition mechanisms like DNS64 and NAT64 help but were initially the primary tools known for IPv6-only networks.
Discovery of 464XLAT's Role
- James set up IPv6-only networks at home using DNS64, NAT64, and later discovered 464XLAT.
- He was amazed that devices like Android, iOS, and macOS have built-in 464XLAT, making IPv6-only networks mostly functional.
