fbsubnet — the syllables fold into one another: "fb" hints at a creator or a namespace, an initialism that could be corporate, communal, or mythic; "subnet" is the quiet, rigorous architecture beneath the visible web, the cartilage of routing where ranges are carved and boundaries enforced. Together they map a territory: a grouped set of addresses, a neighborhood of machines, a microcosm with its own ordinances. The subnet itself is an act of selection — what belongs and what is kept at bay. It is topology as temperament.
