Abstract

An IP address assignment method including assigning a chassis serial number to a node during manufacture, generating an array of unique IP addresses composed using the chassis serial number, and assigning a unique IP address from the array to each interface associated with the node.

Claims

1. An IP address assignment method comprising:

assigning a chassis serial number to a node during manufacture;

generating an array of unique IP addresses composed using said chassis serial number; and

assigning a unique IP address from said array to each interface associated with said node.

2. The method according to claim 1, including:

generating a chassis serial number during manufacturing;

composing a node main IP address based on said chassis serial number, during power-up of the node; and

composing a plurality of associated interface addresses, based on said node IP address.

3. The method according to claim 1, wherein said step of generating an array includes generating a array of 64 unique IP addresses, each including 32 bits.

4. The method according to claim 2, wherein said step of generating an array includes generating a array of 64 unique IP addresses, each including 32 bits.

5. The method according to claim 1, further including reserving a special pool of DHCP IP addresses to be distributed in a LAN network for connection to said node.

6. The method according to claim 2, further including reserving a special pool of DHCP IP addresses to be distributed in a LAN network for connection to said node.

7. The method according to claim 1, further including reserving a special pool of IDCP IP addresses to be distributed to dial-up users for connection to said node.

8. The method according to claim 2, further including reserving a special pool of IDCP IP addresses to be distributed to dial-up users for connection to said node.

9. The method according to claim 2, wherein the IP addresses of each interface is composed from said node main IP Address, a slot number of a card in said node associated with said interface, and a number of a port on the card associated with the interface.

10. A computer program product for IP address assignment comprising:

means for generating an array of unique IP addresses composed using a chassis serial number assigned to a node during manufacture; and

means for assigning a unique IP address from said array to each interface associated with said node.
