Most people don't always get the same IPv4, they get a random one from the ISP, though it is still identifying.
IIRC zeroing the last one or two groups of IPv4 and the /56 or /48 of the IPv6 address block should be fine.
Alternatively you can use a short hash function (xxhash32 cut to 16bits for IPv4 or pure xxhash64) to effectively destroy most of the data but still get a good pseudo-identifier.
