> Is this just baby-talk for non-techies, or does the author really think this is how IP4 addresses are allocated? The former, probably. Nominally, that is how IPv4 addresses are allocated, but the mass of caveats and "but actually"s required is enough to bury it many times over. (For starters, we actually care about network topology, which is only roughly correlated with geography. Additionally, address blocks are typically allocated to organizations, which again correlate only loosely with topology or geography. Those blocks are then subdivided on a basis that slighly relates to topology (but not geography), but only the extent that it helps limit the size of routing tables and BGP data. And of course there's all kinds of other messes mixed in with this as well.)
