Claim:
Method of addressing in a digital telecommunications network having first and second addressing zones between which an interface caters for address translations, comprising the following steps: a name and address server situated in the first addressing zone receives, origination from a first address of the first zone, assigned to a source machine, a request to provide an address in relation to the name of a destination machine; if the destination machine is situated in the second addressing zone, the name and address server sends to a second address of the first zone a first packet containing at least the said name of destination machine; the interface retransmits the first packet to a first address of the second zone, assigned to a management unit and associated in a static manner with the second address of the first zone; the management unit obtains a second address of the second zone assigned to the destination machine whose name appears in the first packet; the management unit sends the interface a second packet destined for the name and address server comprising the second address of the second zone as origin address; the interface transmits the second packet to the name and address server while replacing the origin address by a third address of the first zone, forming part of a list of addresses of the first zone allotted to the second addressing zone and associated in a dynamic manner with the second address of the second zone; the name and address receives the second packet, extracts therefrom the third address forming the origin address, and includes this third address in a response to the address provision returned to the first address of the first zone.
