IP address requirement?

[sysrqb]

(I'm being a little pedantic, sorry in advance).

This document is called IP Reputation, is IP shorthand for IP address? I'm asking because it talks about how IP addresses are used in calculating a reputation, and then the introduction section concludes by saying clients could present proof of reputation that is separate from the IP address, and uniquely bound to a given connection. However, Identity is specifically defined as Any identifying information about an end-user or service [...] including IP addresses.

Questions:

1. Should the definition of Identity be possibly including IP addresses?
2. Can this document decouple Reputation/Identity and IP addresses, or are they fundamentally coupled such that the IP address will always influence a Reputation (even if only by a small amount)?
3. Should this document be renamed as (something like) Client/Connection Reputation, instead of IP Reputation?

Obviously, I want to completely decouple IP addresses and reputation, and I'd like to work towards realizing the ideal solution you described at the end of the intro.
