Despite IPv4 address exhaustion being declared over a decade ago, IPv6 adoption remains stalled. The core reason: NAT solved the client-side address shortage and SNI solved the server-side problem, making IPv4 'good enough' with no compelling business incentive to migrate. IPv6 offers no speed, security, or capability improvements — just larger addresses. Practical IPv6 implementations are often buggy and incomplete, further discouraging adoption. The internet's decentralized, cooperative nature makes forced transitions nearly impossible, and the author sees no clear path to IPv6 dominance in the near future.
