No, it's a technical matter. If the global routing tables get too big then the routers that depend on them have a harder time doing their job. And if four consecutive IP numbers all go out the same interface it makes technical sense to aggregate them from four 24-bit prefixes to one 22-bit prefix. Study that example carefully and you will understand. It may help to write out the IP numbers in binary and look at the bits. > *AND* in order to make these decisions one must have a > mandate.

The people who operate the networks don't want their routing tables full of unneccessary junk.
