Comment 2 for bug 1088611

For anyone who's looking at DNS logs for security purposes, that "random, unqualified 32-character alphanumeric hostname" is going to cause significant issues for anyone trying to figure out what initiated that DNS request. It's also going to look suspiciously like a botnet's DGA. It would be better if these requests made it explicitly clear a) that it's intentionally invalid b) what triggered the request.
