At least at one point in 2003, you also used, eg

finance137-148-212-227.dhcp.csuohio.edu [137.148.212.227]

which kindly pointed out that the IP was dynamically assigned (or at
least suggested it, I know DHCP can push statics, too). I have the
pattern for the csu-n-n-n-n.csuohio.edu naming convention above marked
as 'static/lan' - should I have this down as 'natproxy/unknown' instead?
Or 'static/unknown'? Or 'static/wan'? I'm a bit confused by what it
means to have an "internal" static public IP, I guess. Or are you saying
that they have the option of making their chosen internal name also
visible via external DNS lookups, with all IPs being public just not
all visible via custom names to the outside?
