Techniques to facilitate enhanced addressing of local and network resources from a computing system are provided herein. In one implementation, a method of updating a virtual address mapping for an application on a computing system includes identifying a request to update the address mapping from a first mapping to a second mapping, wherein the first mapping maps virtual addresses to local addresses for local resources. The method further includes identifying at least one configuration resource to support the update, and retrieving an update configuration from the at least one configuration resource. Based on the update configuration, the method provides generating the second mapping, wherein the second mapping maps the virtual addresses to second local addresses for the second local resources and network addresses that address network resources accessible over a network.
