I don't do bogon filtering. I do take a bogon route feed from team cymru,
but that won't stop me from reaching any announced subnets within "bogon
space"[1]. And cymru has been pretty good about keeping up with the
changes wrt what's a bogon and what's not.
What I will do, next time we get space from ARIN (which I suspect isn't
too far off) is setup 72box (or whatever /8 they're allocating from now)
and repeat the exercise I did with 69/8 space so I have some idea where
the idiot networks are (and try contacting them) before we start using or
assigning IP's from that space.
[1] at least not until cisco adds a feature allowing you to ignore new BGP
routes for subnets of a bogon feed.
