Abstract

Mechanisms are provided for assigning addresses for use in communications between computing devices. With these mechanisms, a centralized domain name registrar server assigns a unique global identifier to a domain of a site such that the unique global identifier uniquely identifies the domain. The unique global identifier is received in a data processing system from the centralized domain name registrar server. The site is divided into a plurality of sub-domains and a unique sub-domain identifier is assigned to each sub-domain in the site such that the unique sub-domain identifier uniquely identifies a corresponding sub-domain in the site. The global identifier for the domain of the site and the sub-domain identifiers of the sub-domains in the plurality of sub-domains are provided by the data processing system to routers of the site for use in associating addresses with devices of the site.

Claims16

Dependent claims

A method, in a data processing system, for assigning addresses for use in communications between computing devices, comprising:

assigning, by a centralized domain name registrar server, a unique global identifier to a domain of a site such that the unique global identifier uniquely identifies the domain;
receiving the unique global identifier in the data processing system from the centralized domain name registrar server;
dividing the site into a plurality of sub-domains;
assigning a unique sub-domain identifier to each sub-domain in the site such that the unique sub-domain identifier uniquely identifies a corresponding sub-domain in the site;
providing the global identifier for the domain of the site and the sub-domain identifiers of the sub-domains in the plurality of sub-domains to routers of the site for use in associating addresses with devices of the site;
storing, in a global name server, addresses generated by the routers based on the unique global identifier and unique sub-domain identifiers;
and
providing, by the global name server as part of a name resolution operation, the addresses generated by the routers to the devices for use in communications associated with the devices.

and
assigning, by a router of the site, an address to a device within the site, based on the unique global identifier and a unique sub-domain identifier for a sub-domain in which the device is present in the site, wherein the assigned address is a local address that is not global in scope.
