Systems and method are provided for source-dependent address resolution. Multiple computing devices may be associated with identifiers, such as network names. These computing devices may further be associated with both internally and externally accessible network addresses. A source-dependent address resolution component may resolve a network identifier into an internal or external address based on a network of a requesting device. Specifically, a request for address resolution may be received from a source network, and be resolvable into an address of a target network. If the source network and target network are the same, an internal address of that shared network is returned. If the source network and the target network are different, an external address enabling external communication with the target network is returned. In some embodiments, determination of a source network may be facilitated based on a source port of a request.
