In our peering session with Cogent, we requested several /16 le /24  
prefixes configured and received no pushback or problems. We are using  
their 1Gbps service so I'm not sure if that buys us additional leeway  
with requests like this or not. We've been customers for nearly two  
full years and intend to continue for at least a third.
