Abstract

The present invention assigns appropriate IP addresses to hosts in a local network depending upon the desired features for each host. A list of hosts in the network along with features available for each host may be generated, for example, by a graphical user interface displayed to a user. The user may select a desired feature for a specific host in the network. The selected feature may be analyzed to determine if it requires a static IP address for the host, and if required, a static IP address may be assigned to the host. If the specified feature requiring the static IP address is subsequently disabled, the static IP address may be returned to a pool of available IP addresses, and a dynamic IP address may be assigned to the host. The IP addresses are preferably assigned to the host in accordance with the Dynamic Host Configuration Protocol.

Claims

1. A method for assigning Internet Protocol (IP) addresses, comprising:

identifying hosts present within a local network;

providing a list of available features for at least one host within said local network;

receiving a selection of one of said available features from said list;

a analyzing by an agent if said selected feature requires a static IP address to be assigned to said at least one host; and

assigning an IP address to said at least one host by said agent, wherein a static IP address is assigned to said at least one host if said selected feature requires said static IP address.

2. The method as claimed in claim 1, wherein a dynamic IP address is assigned to said at least one host if said selected feature does not require said static IP address to be assigned to said at least one host.

3. The method as claimed in claim 2, wherein said static IP address is assigned from a pool of available static IP addresses and said dynamic IP address is assigned from a pool of available dynamic addresses.

4. The method as claimed in claim 1, wherein said list is provided in a graphical user interface.

5. The method as claimed in claim 4, wherein said selected feature is capable of being selected by a user utilizing said graphical user interface.

6. The method as claimed in claim 1, wherein said assigning of said IP address is in accordance with Dynamic Host Configuration Protocol.

7. The method as claimed in claim 1, further comprising, returning said static IP address to a pool of available IP addresses if said selected feature requiring said static IP address is disabled.

29. The system of claim 1 wherein said analyzing if said selected feature requires a static IP address is performed automatically.

30. The system of claim 1 wherein said analyzing if said selected feature requires a static IP address is performed without user intervention.

31. The system of claim 1 wherein said list of available features includes blocking access to the Internet from said at least one host.

32. The system of claim 1 wherein said list of available features includes designating said at least one host as a demilitarized zone (DMZ) host.

8. A computer readable storage medium having a program of instructions stored thereon, that when executed cause an information handling system to execute steps for assigning Internet Protocol (IP) addresses, the steps comprising:

identifying hosts present within a local network;

providing a list of available features for at least one host within said local network;

receiving a selection of one of said available features from said list;

analyzing if said selected feature requires a static IP address to be assigned to said at least one host; and

assigning an IP address to said at least one host, wherein a static IP address is assigned to said at least one host if said selected feature requires said static IP address.

9. The computer readable storage medium as claimed in claim 8, wherein a dynamic IP address is assigned to said at least one host if selected feature does not require said static IP address to be assigned to said at least one host.

10. The computer readable storage medium as claimed in claim 9, wherein said static IP address is assigned from a pool of available static IP addresses and said dynamic IP address is assigned from a pool of available dynamic addresses.

11. The computer readable storage medium as claimed in claim 8, wherein said list is provided in a graphical user interface.

12. The computer readable storage medium as claimed in claim 11, wherein said selected feature is capable of being selected by a user utilizing said graphical user interface.

13. The computer readable storage medium as claimed in claim 8, wherein said assigning of said IP address is in accordance with Dynamic Host Configuration Protocol.

14. The computer readable storage medium as claimed in claim 8, further comprising:

returning said static IP address to a pool of available IP addresses if said selected feature requiring said static IP address is disabled.

15. In a local network of one or more one hosts, a system for assigning Internet Protocol (IP) addresses, comprising:

means for identifying the hosts present within the local network;

means for providing a list of available features for at least one host within the local network;

means for receiving a selection of one of said available features from said list;

means for analyzing if said selected feature requires a static IP address to be assigned to said at least one host; and

means for assigning an IP address to said at least one host, wherein a static IP address is assigned to said at least one host if said selected feature requires said static IP address.

16. The system as claimed in claim 15, wherein a dynamic IP address is assigned to said at least one host if said selected feature does not require said static IP address to be assigned to said at least one host.

17. The system as claimed in claim 16, wherein said static IP address is assigned from a pool of available static IP addresses and said dynamic IP address is assigned from a pool of available dynamic addresses.

18. The system as claimed in claim 15, wherein said list is provided in a graphical user interface.

19. The system as claimed in claim 18, wherein said selected feature is capable of being selected by a user utilizing said graphical user interface.

20. The system as claimed in claim 15, wherein said assigning means operates in accordance with Dynamic Host Configuration Protocol.

21. The system as claimed in claim 15, further comprising:

means for returning said static IP address to a pool of available addresses if said selected feature requiring said static IP address is disabled.

22. In a local network of one or more hosts, a system for assigning Internet Protocol (IP) addresses, comprising:

a processor;

a memory coupled to said processor, wherein said memory stores a list of available features for at least one host within the local network;

a display coupled to said processor, wherein said display provides said list of available features to a user;

an input device coupled to said processor, wherein said input device receives a selection by said user of one of said available features from said list;

logic executed by the processor, wherein said logic identifies hosts present within a local network, analyzing if said feature selected by said user requires a static IP address to be assigned to said at least one host, and

assigning an IP address to said at least one host, wherein a static IP address is assigned to said at least one host if said selected feature requires said static IP address.

23. The system as claimed in claim 22, wherein a dynamic IP address is assigned to said at least one host if said selected feature does not require said static IP address to be assigned to said at least one host.

24. The system as claimed in claim 23, wherein said static IP address is assigned from a pool of available static IP addresses and said dynamic IP address is assigned from a pool of available dynamic addresses.

25. The system as claimed in claim 22, wherein said list is provided in a graphical user interface on said display.

26. The system as claimed in claim 25, wherein said selected feature is capable of being selected by said user utilizing said graphical user interface.

27. The system as claimed in claim 22, wherein said IF address is assigned in accordance with Dynamic Host Configuration Protocol.

28. The system as claimed in claim 22, said logic is further capable of returning said static IP address to a pool of available addresses of said selected feature requiring said static IP address is disabled.
