I do it. Reasons are to control inbound traffic better, some routes are annnounced to all upstreams, some are to some specific ones, some have different communities tagged to them, etc. I have one block which is /19 which I do not announce and only announce multiple /23, /24 out of. It works just fine - I'v not seen one place which does not route there...
I was curious how much of the de-aggregation was due to multi-homed companies requiring the longer prefixes. Are there companies that actually announce their smaller routes despite controlling the shorter prefix? What would be the benefit of doing so? -Jack
