An apparatus and method for dynamic sharing of server network interface resources are provided. With the apparatus and method, when a master application server detects a heavy load condition on one or more network interfaces associated with the server computing device, the master application server spawns additional slave application subservers. The network interfaces are distributed across the slave application subservers and are bound to the network interfaces to which they are associated. The master application server continues to listen for traffic on a standard port of all network interfaces. When a new communication connection request is received via a port associated with a network interface, the slave application subserver associated with the network interface will first process the new communication connection request without having to have the master application server route the data packet to the slave application subserver.
