Ask HN: Could Wikipedia show hashed IP addresses instead?

1 points by u-dissolve ↗ HN
When an unregistered Wikipedia user makes a contribution, it shows the IP address from which the edit was made instead of a username. In the interest of privacy, could Wikipedia instead display a hash of the IP address? They could still keep track of an IP address's contributions, and ban them when necessary. IP range blocks could still be issued server-side.

The IP addresses of registered users are hidden anyways (accessible only by a few certain users, and only if warranted[1]), so could Wikipedia offer this to all users?

It would be trivial to brute force, so almost pointless.

Yes, but brute forcing would take longer to do. Could they also hash it, say, a few thousand times in order to increase the cost of brute forcing?

Isn't some layer of obfuscation better than a bare IP address?
