The Interuniversal Trolliverse Internet (ITN) is the internet used in the Trolliverse area. Because of its vastness, setting up an internet in the Trolliverse was quite a challenge for computer scientists, but they could finally build the Interuniversal Trolliverse Internet.
Connection between computers in all of the Trolliverse Area is done using wormhole telecommunications, which allows a signal, limited by the speed of light, to travel through a wormhold to reach its destination faster.
Interuniversal Trolliverse Internet is only accessable if you live in the Trolliverse Area in the Known Dimension, so it won't work from Earth.
