Abstract
A method for resolving an IP address, includes a step of receiving an address resolution request, the request including a datum representative of a MAC address; a step of looking up, within a data structure, an IP address, depending on the datum representative of a MAC address; and a step of transmitting said IP address.
Claims8
A method for resolving an IP address, characterized in that it comprises:
- a step (21) of receiving, by a DNS server, an address resolution request, said request comprising a datum representative of a MAC address, in which said MAC address identifies a communicating object connected to a wireless local area network, said wireless local area network being based on an addressed communication protocol using said MAC address and different from IP, wherein said wireless local area network does not use the IP, said datum representative of a MAC address having the form of a domain name, said domain name being composed of at least two successive domains:
- a first lower-level domain, formed from said MAC address;
- at least one predetermined top-level domain;
- a step (22) of looking up, within a database of addresses of the DNS server, an IP address, depending on said datum representative of a MAC address, in which said IP address identifies a device with which said communicating object has to exchange data;
- a step (23) of transmitting said IP address, by the DNS server, to a gateway interconnecting the wireless local area network through a network interface employing said addressed communication protocol different from IP with an IP wide area network.

A system for resolving an IP address, comprising:
- a communicating object connected to a wireless local area network, wherein said communicating object is identified by a MAC address, said wireless local area network being based on an addressed communication protocol using the MAC address and different from IP;
- wherein said wireless local area network does not use the IP,
- a gateway, said gateway comprising
- a first network interface connected to the wireless local area network;
- a second network interface connected to an IP wide area network
- a DNS server, said DNS server comprising
- means for receiving an address resolution request, said request comprising a datum representative of the MAC address, said datum representative of the MAC address having the form of a domain name, said domain name being composed of at least two successive domains:
- a first lower-level domain, formed from said MAC address;
- at least one predetermined top-level domain;
- means for looking up, within a database of addresses of the DNS server, an IP address, depending on said datum representative of a MAC address, said IP address identifying a device with which said communicating object has to exchange data;
- means for transmitting said IP address to said gateway interconnecting the wireless local area network with the IP wide area network.
