Joe,

Firstly thanks for getting back to me.

I think there is still a serious design flaw which in practise will make the scheme unusable for your BGP work.

You explicitly call out the need for the CIDR hierarchy and DNS hierarchy to align ("Coverage Authority") in §3 and §4.2 of your draft and claim that your scheme provides this, but it's easy to construct examples where that's not true.

Hence my concern is that the DNS scheme you have proposed _simply doesn't work_.

IMHO, it would be premature to enter into detailed discussion with the operational community until this hierarchy problem is resolved.

kind regards,

Ray
