Ok, before someone else gets saddled with this problem... ARIN pulled the
157.156.0.0/16 from their database. Spam-afficienados would recognize this
as 'VMX Networks'. ARIN has decided it seems that 157.156.0.0/16 is not
actually registered to the modern day VMX, so, if they come visit your
sales staff for a connection using this ip block (or 134.33.0.0/16 which
is also invalid currently) you might want to carefully consider accepting
the routes
