A computer configured to provide caller-specific network views, even when multiple callers are active on the computer. The operating system of the computer is configured to selectively perform network operations based on the identity of the caller. Network views are implemented by making subsets of networking objects available to each caller, such as a user or an application. Components that execute networking functions can, based on the identify of the caller, select networking objects to use in performing a requested function or verify that required networking objects are available to the caller. The network views may be stored as visibility masks in a database. APIs may be provided to create, modify, and delete visibility masks in the database. The masks may support arbitrary and potentially overlapping subsets of networking objects for the callers.
