Hi Simon,
Considering some developers who made assumptions about undocumented API behavior in the past, and run into pain points when it changed, I just wanted to throw in a couple thoughts here to help you make decisions.
Steve mentioned that we currently anonymize the IP addresses, but nothing guarantees that we anonymize these in the
API design or
terms of service. Given that it's just an implementation detail, you should be careful if you are trying to rely on this for any sort of legal compliance or to meet your company's privacy policies. The docs and APIs are updated frequently and you should keep an eye on them, as well as the
release notes, for changes.
