The K4 uses the same IP addresses as the K5, and for the same reason. Diags expects the 15 subnet.
The IP collisions for SSH keys really does suck, and my less-than-ideal fix was to symlink the key file on my host PC to /dev/null so it is always detected as a new key. Not painless, but at least it works.
