109/8 - not a BOGON

I've found pinging a polite email to the whois contact on the ASN - 
sometimes- gives useful results, but not always.

Be aware that you're not only dealing with router black-holes, but  
seemingly some people have applied bogon filtering to their BIND name  
servers also.

If you can provide a non bogon IP within the same AS, it can be useful  
for the person at the other end-- shows them they have a problem.
