I think the more general point here (and has come up in other contexts
such as mobile phones) is that sometimes neither IP nor reverse DNS make
sense and people would like sending something else to be 'smoother' (as
opposed to hacky/spoofy).
My experience with vendor data hasn't given me warm and fuzzies either
("TO BE ENTERED BY O.E.M") but I could see something like UUID on
startup and 'custom bits on the motherboard' as reasonable -- if not
common -- use cases.

Get your SQL database under version control now!
Version control is standard for application code, but databases havent
caught up. So what steps can you take to put your SQL databases under
version control? Why should you start doing it? Read more to find out.
