Disclosed are various embodiments for providing split-tunneled network connectivity on a per-application basis. A request to make a connection, such as a transmission control protocol (TCP) or a universal datagram protocol (UDP) connection, to a remote host specified by an internet protocol (IP) address in the request is received from a network driver. A hostname lookup table is queried to determine a hostname associated with the IP address for the remote host. A policy is identified based on the hostname associated with the IP address for the remote host. Then, the connection is routed based on the policy.
