What is the most standard subnet length on internet

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"

Chi Young, let me clarify one thing here ..
Do you mean IP allocation as in subnet allocation, swipping in apnic
or through a rwhois server etc?
Or do you mean "what is the minimum subnet size I can announce on the
internet and have other providers not drop it on the floor"?
