Abstract: A method of automatically assigning IP in a ship ad-hoc network includes (A) receiving a non-duplicate IP block from a terrestrial station by transmitting/receiving an IP request signal and an IP request response signal generated from a data link layer by one-hop ship stations able to perform direct transmission/reception with the terrestrial station; (B) allowing the one-hop ship stations receiving IP blocks to determine IPs thereof and to allocate IP blocks, as IP providers, to multi-hop ship stations able to perform indirect transmission/reception with the terrestrial station through ad-hoc communication when the multi-hop ship stations request the IP blocks; and (C) determining one of the IP providers to transmit an IP request signal such that the determined IP provider transmits an IP request response signal when multi-hop ship stations, to which the IP blocks are not allocated, receive MAC frames of plural IP providers in a channel allocation.
