This would be so useful. I once tried to get this information from a company you've all heard of, so that we could reliably whitelist their services on our corporate firewall, and the answer was "they're dynamic, so that's impossible". I said "but you know them, you could dynamically make that information available to your customers", but got nowhere. I'd like this to be a regulatory requirement, but the people who make the rules aren't sufficiently technically competent to identify technical solutions, and don't seem to listen to people who are.

[Edit to add: I really like your old-school approach to building online community for yourself. I don't know your interests, or if I'd like yours, but I wish more spaces with your approach were around. The world in general (not only the internet) is a better place when we interact with each other in ways that aren't commercially determined.]
