Using unique local unicast addresses in a global domain name server

A computer program product comprising a non-transitory computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on a data processing system, causes the data processing system to:

• send a request, from a resolver executing on the data processing system, to a global domain name server requesting a resolution of a domain name into an address;
• receive a response to the request from the global domain name server, wherein the response includes a local address, wherein the local address has a scope that is local to a site associated with the resolver and is not global in scope;
• determine whether the local address corresponds to a domain associated with the resolver;
• and
• perform communications with a device corresponding to the domain name using the local address in response to a determination that the local address corresponds to a domain associated with the resolver.

An apparatus, comprising:

• a processor;
• and
• a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to:
• send a request, from a resolver executing on the data processing system, to a global domain name server requesting a resolution of a domain name into an address;
• receive a response to the request from the global domain name server, wherein the response includes a local address, wherein the local address has a scope that is local to a site associated with the resolver and is not global in scope;
• determine whether the local address corresponds to a domain associated with the resolver;
• and
• perform communications with a device corresponding to the domain name using the local address in response to a determination that the local address corresponds to a domain associated with the resolver.
