Hm, it will allow to match any location, what it does with that later
depends on your settings. Putting "reject" as the method will, well,
Also, I use "host dbname username 0.0.0.0/0 md5" in quite a few places,
and I believe I know what I'm doing. ;-)

Sorry, I can't agree here. I need that!
Kind of offtopic:

> /16 : IP must ends with .0.0
Precisely, /24 is A.B.C.*, /16 is A.B.*.*, /8 is A.*.*.*. It's not just .0
or .0.0, it's "anything".
HTH too. ;-)
