Techniques for securing name resolution technologies and for ensuring that name resolution technologies can function in modern networks that have a plurality of overlay networks accessible via a single network interface. In accordance with some of the principles described herein, a set of resolution parameters may be implemented by a user to be used during a name resolution process. In some implementations, when an identifier is obtained for a network resource, the identifier may be stored in a cache with resolution parameters that were used in obtaining the identifier. When a new name resolution request is received, the cache may be examined to determine whether a corresponding second identifier is in the cache, and whether resolution parameters used to retrieve the second identifier in the cache match the resolution parameters for the new resolution request. If so, the second identifier may be returned from the cache.
