He said it was for multiple sites. Per ARIN policy, the next biggest chunk from a /48 is a /44, so a /44 is what should be asked for. It is perfectly justifiable if you have more than 1 site. I would not expect anything smaller than a /48 to be allowed in BGP. A bonus would be that a /44 currently costs the same as a /48 for an enduser, so there really is no drawback from getting the /44, and having enough space to not have to worry about it in the future. -Randy
