An example method includes receiving a domain name server (DNS) query initiated by an endpoint device, determining a current port assignment for the endpoint device, changing an allocation of ports for the endpoint device from the current port assignment based on a predicted port allocation need for a current communication session associated with the domain name server query, and performing a network address translation in accordance with the allocation of ports for the endpoint device.

Dynamic port allocations in carrier grade network address translation networks

Aspects of the subject disclosure may include, for example, specification of network service functions (e.g., a firewall or network address translation appliance) to be included in a service function path. Routers in a communication network may publish information regarding reachable network service functions and an API may be exposed that provides the information regarding the reachable network service functions. Other embodiments are disclosed.
