The first Interplanetary Net was the InterPlaNet, Interplanetary Network (IPN) in Solsys. This was an extension of Earth's Internet to CisLunar and interplanetary space during the Information Age.
Sinca that time interplanetary nets have been established in almost every system in the Terragen Sphere, operated by a wide range of institutions and other entities. All the various metaempires maintain inteplanetary nets within their systems, and most independent systems do likewise.
Most of these nets are connected to the Known Net, or to one or more of the alternate networks which operate outside that network. Rapid connections are generally routed via wormholes, while slower links are made via the Lightways.
Internet, The - Text by M. Alan Kazlev Old Earth Information Age data-network enabling exchange of information through data packages transmitted through computers linked by telephone and communication satellites, using a common shared protocol. The Internet eventually became a part of the IPN, which in term was later expanded to become the Interstellar Net and finally the Known Net.
Local Net - Text by M. Alan Kazlev Sometimes as a single word, 'localnet'. Refers to any local subnet of the Known Net. May range from a single habitat intranet to a polity, planetary or interplanetary net.
