Method, apparatus, and system for reassigning a network address

An apparatus comprising:

• a detection module detecting a routing table change for a host, wherein the host is in communication with at least one network and a client is in communication with the host over a network interface using a first address;
• a generation module generating a second address for the client, wherein the second address does not compete with other addresses on the at least one network;
• an interface module disabling the network interface to the client and enabling the network interface between the client and the host;
• and
• a communication module receiving a request for a new address from the client and assigning the second address to the client.

A system comprising:

• a client being in communication with a host through a network interface using a first address;
• at least one network being in communication with the host;
• the host comprising
• a detection module detecting a routing table change for the host;
• a generation module generating a second address for the client, wherein the second address does not compete with other addresses on the at least one network, the second network address being generated from a list of possible networks, wherein unsuitable networks are removed from the list of possible networks are by comparing each network in the list of possible networks with each entry in the routing table and removing a first network from the list of possible networks if the net mask for a first entry in the routing table is not equal to ‘0.0.0.0’ and if a logical AND of an address of the at least one network and the first entry net mask is equal to the first entry;
• an interface module disabling the network interface to the client and enabling the network interface between the client and the host;
• and
• a communication module receiving a request for a new address from the client and assigning the second address to the client.
