So to start off, I'm new to following this list so if these points have already been beaten into the ground, feel free to tell me to shut up.
So two things I wonder about the preservation of current IP4 space and delaying IP6 are: 1. Why don't providers use /31 addresses for P2P links? This works fine per rfc 3021 but nobody seems to believe it or use it. Are there any major manufacturers out there that do not support it? 2. Longer than /24 prefixes in global BGP table. The most obvious answer is that some hardware may not handle it... How is that hardware going to handle an IP6 table then? I have had several occasions where functionally I needed to advertise for different sites but only needed 20-30 addresses which is a complete waste of a /24. How hard would it be to start allowing /25s when compared to trying to roll out IP6? The intention of this isn't to start a "what's good or bad about IP6 and what still doesn't work" debate.. I'm just generally curious about how these two seem like easy ways to make more efficient use of what we have already.
