1. A method in a data processing system for managing network addresses, the method comprising:
- comparing a received network address from a current server for use in identifying the data processing system with a prior network address from a previous server;
creating a release data packet if the received network address is a new network address and the previous server is a different server than the current server, wherein the release data packet includes the prior network address; and
sending the release data packet to the previous server, wherein the release data packet causes the previous server to release the prior network address for reuse.

Abstract
A method, apparatus, and computer instructions for managing network addresses. A received network address from a current server is compared for use in identifying the data processing system with a prior network address from a previous server. A release data packet is created if the received network address is a new network address and the previous server is a different server than the current server in which the release data packet includes the prior network address. The release data packet is sent to the previous server in which the release data packet causes the previous server to release the prior network address for reuse.

7. A data processing system for managing network addresses, the data processing system comprising:
-
a bus system;
a communications unit connected to the bus system;
a memory connected to the bus system, wherein the memory includes a set of instructions; and
a processing unit connected to the bus system, wherein the processing unit executes the set of instructions to compare a received network address from a current server for use in identifying the data processing system with a prior network address from a previous server;
create a release data packet if the received network address is a new network address and the previous server is a different server than the current server in which the release data packet includes the prior network address; and
send the release data packet to the previous server in which the release data packet causes the previous server to release the prior network address for reuse.
