There were none of those involved in this.
Having seen IOS versions that refused to forward traffic for .255
destinations, when the .255 was in the IGP as a /32 (even with ip
classless in the config), I've since avoided using .0 or .255 addresses.
It seems classful routing may be dead, but not entirely forgotten.
