 *'''Latency'''.  One specific particularity on an Internet between Mars and the Earth is the communications latency.  Due to speed of light limitation, there is necessarily a lag of 4 to 15 minutes in one direction and 8 to 30 minutes in bi-directional communications.  This means it is impossible to get quick information from a central server on Earth, and that much of the Internet's data will need to be replicated on Mars. This will require large amounts of data storage and access protocols.

−	~~==In fiction==~~
−
−	In the Star Trek universe, members of the United Federation of Planets often send messages, in a generally instantaneous manner. An example would be a character (e.g. James Kirk or Jean-Luc Picard) speaking with another Federation officer tens, hundreds or even thousands of light years away. Whilst this is evidently a fictional scenario, it depicts in theory what an interplanetary Internet could look like, or at the least how communication between networks and hosts could occur over vast distances.
