Efficient (Dense) Use of Address Blocks

What percentage of the individual host addresses are currently used by functioning hosts (or router interfaces)? Perhaps you're both saying you re-assigned use of these address blocks quickly, rather than saying you populated them densely with actual hosts? One could imagine ISPs (not Karl or Alan, surely!) who might re-assign blocks of class C (octet-wide) networks when a single one would suffice. Or they might assign octet-wide networks when quartet-wide (nibble) networks would suffice; or even quartet-wide networks when triplet-wide networks would suffice. I believe ISPs who receive large blocks have a responsibility to make sure they (and their customers) use them efficiently. How efficiently, you ask? If you're not getting more than one U.S. dollar of value per host address per year, you're not using it efficiently in my book! -- Sean Shapira [email protected] +1 206 443 2028 <a href="http://www.jazzie.com/sds/">Sean's Home Page</a> Serving the Net since 1990.
