1. A method of providing a naming service inside an industrial communication system comprising subordinate subnetworks, superordinate subnetworks, communication terminals, and routers, the method comprising: distributing IPv6 prefixes in the respectively subordinate subnetworks via routers with messages containing router advertisements, the router advertisements comprising a topological and/or hierarchical name component of the respective router, and the topological and/or hierarchical name component being associated with a spatial or hierarchical arrangement of the respective router; receiving router advertisements containing name information from superordinate subnetworks by routers associated with the subordinate subnetworks; supplementing the router advertisements with a topological and/or hierarchical name component associated with the respective router; distributing the supplemented router advertisements inside the respective subordinate subnetwork; and independently generating, by communication terminals, their device name from topological and/or hierarchical name components and a unique name component inside their respective subnetwork; wherein the router advertisements containing name information from superordinate subnetworks are received by routers associated with subordinate subnetworks by a respective functional unit for implementing a distributed naming service; wherein at least one topological and/or hierarchical name component is made available to at least one router by at least one DHCPv6 server and is distributed by said router.
