In some examples, a controller obtains an Internet Protocol (IP) address of a compute entity that is to communicate over a network, and determines a role for the compute entity by accessing, using the obtained IP address, a role mapping data structure that maps IP addresses to roles. The controller adds the determined role to network address mapping information in the network, the network address mapping information including entries having respective network addresses, the determined role in the network address mapping information for use by a network device of the network in applying policy enforcement for traffic through the network device.
