Something to note is that it's not just the DLC, the patch that released alongside it introduced a slew of bugs to everyone who owns the game. Apparently this includes framerate now affecting things like movement speeds, enemies sometimes dealing insane bursts of damage randomly, invisible enemy projectiles, among other gameplay breaking stuff. Total disaster.
Sigh... I guess we saw it coming with Gearbox...
That's called an intranet (which is like the internet but for a building or small area).
The internet isn't really anything more than computers connected to other computers. If you want to make your own internet you can connect two computers whether wired or wireless, and voila. You can host a website locally that only those two computers can access.
