The author mentions it's a violation of GDPR to record visitors' IP addresses. I'm not sure that's correct, but even so, it could be possible to make a custom encoding of literally every ipv4 address through some kind of lookup table with 256 entries, and just string together 4 of those random words to represent the entire 32-bit address space, such that "correct horse battery staple" corresponds to 192.168.1.100 or whatever.
