Re: [DNSOP] Draft DNSOP Meeting Minutes

Hi Tim,

Some small comments below. These are not suggested revisions to the minutes, but rather points that derive from them.

This is my recollection of the outcome of that discussion, but subsequent (off-list) discussion suggests that the chairs' recollection is that the working group agreed to adopt "the issue", and to defer adoption of the documents until clarity on the practicality of the DNAME approach is achieved.

I'm happy either way (I'm not sure I understand what "wg adopts an issue" means, however) but it seems reasonable to ask the Chairs to (a) clarify, and (b) ask the list what people want.

I think the phrase was "this is the worst idea I have ever heard of". :-)

Warren and I have started discussing next steps. Our thought is to start with a problem statement and some working requirements, and then to think about solutions. If others are interested in helping to frame the question (with the goal of bringing the results to the working group for discussion) please let one of us know.
