In its original configuration, the Extranet was fitted to accomodate ten passengers (in a cramped rapid transit configuration) in addition to its pilot; Aren has removed four of the seats in favour of a futon so he can rest during long trips (although, due to their expense, no quarian-level clean-room facilities have been installed). It has a decent volume of cargo space, an upgraded FTL plotter and pilot assist VI (installed by Aren), and an internal security system incorporating a concealed turret covering the entryway (courtesy of its former owner). Its engines are unremarkable, and it carries the bare minimum of ship-to-ship defences necessary to safeguard against meteorite impacts and discourage opportunistic pirates.
The ship's current name was chosen by Aren's co-workers, so that whenever he returns from Illium they can say "Oh <expletive>, the Extranet is here," echoing a meme which gained some popularity after the Discori operation.
The image representing the Extranet is modified from a cargo shuttle seen in Star Trek: Enterprise.
