Ask HN: How do I anonymize a user's IP Address?

a) please do not delete & repost, it's against HNs rules

b) You can't maintain a 1:1 mapping and anonymity, if I know your algorithm it's trivial to try all IP addresses and get a mapping to do a reverse look up. You need to throw away data to make it ambiguous, e.g. in probabilistic data structures like bloom filters.

I don't know what a snooper would want with the HTTP referrer information.

didn't delete. I edited my other question (which has a different focus) and then posted this.

Ok, sorry, I just remembered seeing the question shortly before and couldn't find it again ;)
