And now you have a nonsense IP that's almost impossible to crack.
No. You have a nonsense IP that anyone with the slightest determination
can reverse-engineer. As I previously mentioned, you have two ways of
ensuring strong anonymity. You can hide the IP completely from visitors,
and just allow the admins to see it, or you can use an asymmetric cipher
with a site-wide password. The latter option has the advantage that you
can salt with another known property of the edit - say, timestamp - to
get a new per-edit identifier for the same IP each time, avoiding the
problem with Brent's solution.
While it may well be enough for the level of anonymity you're striving
for, claiming that your makeshift cryptographic hand-waving is "almost
impossible to crack" is, at the very least, ignorant.
