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

Ted - thanks for posting a clear summary of the situation for WG discussion and consensus.  Two questions in line…

The reason is that we need DNS resolution to work properly for domains under .homenet, and this has to work even if a host is doing DNSSEC validation.

The reason for this is that the root zone provides proof of nonexistence for nonexistent names in that zone.

The problem is that from a process perspective, this is a _lot_ more heavyweight than doing a special-use domain name allocation, and has no guarantee of success.   This wasn't such an issue for .onion when we did it, because .onion _wants_ a secure denial of existence--we _never_ want a .onion query to actually happen if the name has been handed to a resolver that doesn't understand .onion explicitly.   This is not true for .homenet.

The other is to take the more expedient, less satisfying approach: use .home.arpa instead of .homenet.   I'm not in love with this as an end solution, but it has the advantage that the IAB controls .arpa, and so we can get an unsecure delegation right away assuming the IAB agrees.   I see no reason to think they would not.   It's a bit more typing, and there is the problem that the fourth google result for arpa is "Advanced Research Projects Agency.   But it would work, and quickly, and would keep the whole process in the family.

The downside to this approach is that we won't know whether the outcome will be success or failure for a long time, possibly several years.   And the outcome could very well be failure.   The upside is that we get the name we all want; the downside is that we are a long way down the road with no win.

So, now I’m a little confused by the alternatives; for clarity, does the paragraph that begins “The other alternative” refer back to the “ask ICANN to do the delegation” approach?

Are you referring to “.home”, “.homenet”, “.home.arpa” or some other name to use as the HNCP default?

> So I am personally okay with either decision.   Our AD, Terry, may have more of a sense of what ICANN will do (but to some extent he really can't know, because it's up to committees within ICANN to actually make this decision).   I'm mentioning this now not to derail the process, but simply to make it really clear what our expectations should be.   The reason that this didn't come up in Seoul is that it didn't actually click for me that we had a serious problem until several of us were chatting on the way out of the room, after the working group had already decided to proceed.
