Verizon Business FiOS, in their infinite wisdom, has assigned me

  72.64.118.112/29

(Actually, they just told me that I've got 72.64.118.114-118)

They have told me that my gateway is 72.64.118.1

They only way I've been able to get things to work is by lying about  
my WAN configuration, and assigning 72.64.118.1/25 to it.

This works fine.  But of course it will fail if I ever try to contact  
anything in the /25 range that isn't in my true /29 range.  That is  
unlikely, but still in principle this bothers me.  I am going to  
attempt to reach Verizon customer support for other reasons, but can  
someone point me to the relevant RFC I can cite when I tell them that  
their arrangement is broken?

If people have useful experience dealing with ISPs about this kind of  
problem, I'd be happy to listen to any advice.
