Abstract

Exemplary embodiments are directed to generating Internet Protocol (IP) addresses using a mask that is applied to a plurality IP addresses to generate plural groups of IP addresses. A range of IP addresses is generated for each of the groups when the plurality of groups is less than or equal to a predetermined number of groups. When a range of IP addresses is selected from the plurality of ranges IP addresses, the network nodes associated with the selected range are displayed.

3. The method of claim 2, wherein the mask identifies a first portion of an IP address to be masked and the another mask identifies a second portion of the IP address to be masked, wherein the second portion includes the first portion.

4. The method of claim 1 comprising:

selecting, by the processor, a range of IP addresses from the plurality of ranges of IP addresses; and

displaying network nodes associated with the selected range.

5. The method of claim 1, wherein applying the mask comprises:

performing, by the processor, a logical AND operation between each of the plurality of IP addresses and the mask to generate a resultant IP address, wherein the resultant IP address identifies one of the plurality of groups of IP addresses.

6. The method of claim 1, wherein applying the mask comprises:

applying the mask, by the processor, to the plurality of IP addresses to generate a plurality of masked IP addresses; and

grouping masked IP addresses to generate the plurality of groups of IP addresses.

7. The method of claim 6, wherein the mask identifies a first portion of an IP address to be masked and a second portion of the IP address, and wherein the masked IP addresses are grouped based upon the second portion of the IP addresses.

8. A management station for generating ranges of Internet Protocol (IP) addresses comprising:

a memory which stores a plurality of IP addresses; and

a processor which receives the plurality of IP addresses and applies a mask to the plurality of IP addresses to generate a plurality of groups of IP addresses, and which generates a range of IP addresses for each of the plurality of groups, generation of the range based on the groups of the plurality of groups being less than or equal in number to a predetermined number of groups;

wherein the range for each group is generated based on a difference of the IP addresses already in the group.

9. The management station of claim 8 wherein the processor applies another mask to the plurality of groups of IP addresses to generate another plurality of groups of IP addresses, application of the another mask based on the groups of the plurality of groups being greater in number than the predetermined number of groups, and generates new ranges of IP addresses using the another plurality of groups, generation of new ranges based on the groups of the another plurality of groups being less in number than the predetermined number of groups.

10. The management station of claim 9, wherein the mask identifies a first portion of an IP address to be masked and the another mask identifies a second portion of the IP address to be masked, wherein the second portion includes the first portion.

11. The management station of claim 8 comprising:

an input which receives a selection of a range of IP addresses from the plurality of ranges of IP addresses; and

a display which displays network nodes associated with the selected range.

12. The management station of claim 8, wherein the application of the mask includes the processor performing a logical AND operation between each of the plurality of IP addresses and the mask to generate a resultant IP address, wherein the resultant IP address identifies one of the plurality of groups of IP addresses.

13. The management station of claim 8, wherein the application of the mask includes applying the mask to the plurality of IP addresses to generate a plurality of masked IP addresses, and grouping masked IP addresses to generate the plurality of groups of IP addresses.

14. The management of claim 13, wherein the mask identifies a first portion of an IP address to be masked and a second portion of the IP address, and wherein the masked IP addresses are grouped based upon the second portion of the IP addresses.

15. A non-transitory computer readable storage medium containing a computer program for generating ranges of Internet Protocol (IP) addresses, the computer program comprising instructions for:

applying a mask to a plurality of IP addresses to generate a plurality of groups of IP addresses; and

generating a range of IP addresses for each of the plurality of groups the generating based on the groups of the plurality of groups being less than or equal in number to a predetermined number of groups;

wherein the range for each group is generated based on a difference of the IP addresses already in the group.

16. The computer readable storage medium of claim 15 further comprising instructions for:

applying another mask to the plurality of groups of IP addresses to generate another plurality of groups of IP addresses, the applying another mask based on the groups of the plurality of groups being greater in number than the predetermined number of groups; and

generating new ranges of IP addresses using the another plurality of groups, the generating new ranges based on the groups of the another plurality of groups being less in number than the predetermined number of groups.

17. The computer readable storage medium of claim 16, wherein the mask identifies a first portion of an IP address to be masked and the another mask identifies a second portion of the IP address to be masked, wherein the second portion includes the first portion.

18. The computer readable storage medium of claim 15 further comprising instructions for:

selecting a range of IP addresses from the plurality of ranges of IP addresses; and

displaying network nodes associated with the selected range.

19. The computer readable storage medium of claim 15, wherein the instructions for applying the mask comprise instructions for:
