Claim:
1. A method, comprising: hosting, at a validation server, a local domain name service and network time protocol service; determining, by the validation server in a computer network, that an edge router of the computer network is blocking access to a desired server address based on the edge router not having authentication information for the desired server address; based on determining that the edge router is blocking access, dynamically creating at and by the validation server itself, a white-listing policy to temporarily allow access to the desired server address at the edge router, wherein the validation server uses the local domain name service and network time protocol service to create the white-listing policy; sending, by the validation server, the white-listing policy to the edge router; performing server fetching operations to the desired server address from the validation server while the white-listing policy is in effect; and sending instructions from the validation server to the edge device to remove the white-listing policy once the server fetching operations are completed.
