Re: [DNSOP] [homenet] WGLC on "redact" and "homenet-dot"

Mike,

A query to the root for .homenet results in a *signed* answer that .homenet does not exist.  This should suffice for the purpose you have in mind.

Ralph,

Re moving to the homenet list, I will try to send the same info there once I have time to sign up for that list.

The reason we want an unsecured delegation for .homenet is that .homenet can't be validated using the root trust anchor, because the name is has no globally unique meaning.   So the reason that you've given doesn't apply to this case, although I completely agree with your reason as it applies to the case of names that are globally unique.

Most of the major ccTLDs are signed and many of the others are too.  Detailed maps are created every week by ISOC.

It also asks IANA for an unsecured delegation in the root zone to avoid DNSSEC validation failures for local names under “.homenet”. The root zone request to IANA has caused some discussion within the WG, as there’s no precedent for such a request.
