Abstract

Systems, methods, and software are included herein to manage domain name system (DNS) requests to DNS servers. In one implementation, a computing device joins a local network and identifies a connection to a first DNS server associated with the local network. The computing device further implements first DNS rules based on the connection to the first server and monitors when a second DNS server is available using the local network. When the second DNS server becomes available, the computing device implements second DNS rules in place of the first DNS rules, wherein the second DNS rules direct DNS requests to the second DNS server in place of the first DNS server.
