  • code that initiates sending of data to a service at a first domain name, the first domain name being predetermined;

    code that obtains a first network address by performing a domain name system (DNS) lookup on the first domain name;

    code that determines whether the first network address is in a predetermined redirection network address range, the predetermined redirection network address range being unroutable by the network;

    code that obtains a second domain name by performing a reverse DNS lookup on the first network address when the first network address is in the predetermined redirection network address range, the second domain name being returned based at least in part on an availability of the service through the second domain name;

    code that obtains a second network address by performing a DNS lookup on the second domain name, the second network address being routable by the network;

    code that configures a network address translation (NAT) filter of the computing device to establish a rule that routes between the first network address and the second network address; and
