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:
