Suresh, Yes, I guess my concern is close to the second meaning.It seems so simple. Currently annoucement of /24 seems to be okey, most upstream providers accept this. However I wonder if there is any ground rule based on any standard or official recommandation. If there is some standardized rule about prefix length to be annouced, I will make my bgp & IP allocation policy of each data center of my company, and I will be able to more fairly and squarely speak to my customer like this "You have to change your server's IP address if you want move your server to other place"
Some useful guidance is provided here (and in subsequent references) as well: An Architecture for IP Address Allocation with CIDR <http://tools.ietf.org/html/rfc1518>Classless Inter-Domain Routing (CIDR): an Address Assignment and Aggregation Strategy
