What is the "this" to which you refer?I think Mark means "the question of whether a particular address is statically-assigned or dynamically-assigned", but...
Which assumes that that's the question that actually needs to be answered.
The problem space here is what's important. And I think it's worth considering that port 25 isn't the only abuse vector anymore.... I agree that there's no clear limit to the kind of questions we could come up with that we could answer in such a way. Maybe we don't need to boil the ocean, though.
Sure, but positing the deployment of any infrastructure comes at a huge cost. Making certain that you're solving the right problem should be the first concern, since it's so expensive.
$ORIGIN 90.212.90.in-addr.arpa. @ SOA ... @ NS ... ; 13 PTR calamari.hopcount.ca. 13 HINFO Apple-Mac-Mini "Mac OS X Server" 13 RP jabley.hopcount.ca. . 13 TXT "dynamic"
See, that makes the assumption that that is the right question. Is it really though? Dynamic vs static is a placeholder for "authorized for this role or not", right? And not a very good one when you start to consider the larger world of protocols. I don't think it's "boiling the ocean" to ask the question of what the producers and consumers of that information are actually looking for. Mike
