Re: @AC
@ShelLuser under GDPR an IP address is considered PII, so collecting IP addresses over analytics definitely falls under GDPR.
Current recommendations from the IETF for collecting IP addresses (locally on the server, in the logs) is that the IP address be anonymized (i.e. the full IP address is not stored) and that the data be deleted within 3 days.
I can't see Google complying with such a scheme.
