1. Ah, OK, that's useful. I was thinking that dropping the last byte of the IP address would still be able to give us the country via database lookup, but anonymise enough. But getting it via CF (or similar) would be a good alternative.

2. Chances of a hash collision on IP address is pretty small (i.e. statistically insignificant). But adding a daily salt would decrease the odds, for sure.

3. Sorry, my bad, I meant Cloudfront, but it's Sunday night here and there has been wine ;) Same question: how has Cloud{{thing}} worked out for you? Is it worth the extra complexity?

The problem, as I understand GP, is not so much the fear that two different IPs might collide. The problem is that seeing the same hash, you know that it refers to the same IP, and as such you can correlate users/sites over time (a privacy invasion).

That makes sense, kinda. Though I'm a little unsure why correlating http requests over an hour is not invading privacy, but doing the same over a week is?
