Maybe I'm going to have a case of stick-foot-in-mouth disease so:
<setenv flameproof_panties=ON>  :-)

This only works for a certain percentage of networks.  Most likely a
higher percentage post tech bubble collapse.  I used to work for a company
that had 167.216.128.0/17 and we announced that globally.  So you couldn't
say 167.216.128.0/17 was in the US (or even NA) as it'd appear from ARIN
or other data sources.


When you look up that network in ftp://ftp.arin.net/pub/stats/arin/delegated-arin-latest you get

grep 167.216.128.0 delegated-arin-latest
arin|US|ipv4|167.216.128.0|4096|20000531|allocated

I.e. Actually no /17 but 167.216.128.0/20 and based in US. q.e.d.
