Abstract

Apparatus, systems, and methods assign a permanent network address to a user identity, detect access to a network by a node associated with the user identity, generate an identifier associated with the user identity, and send the identifier to the node to enable the node to obtain replacement of a temporary network address allocated to the node, with the permanent network address. Activities may include receiving a release request from a node to release a temporary network address allocated to the node (associated with the user identity), receiving an allocation request (including the identifier) from the node to allocate a permanent network address previously assigned to the user identity, and allocating the permanent network address to the node as a replacement for the temporary network address. Additional apparatus, systems, and methods are disclosed.

Claims

1. A system, comprising:

a first node to access a storage unit to store a plurality of mapping lists, at least one of the plurality including one or more permanent network addresses assigned to a user identity;

a generator module to generate an identifier associated with the user identity when access to a network by a second node associated with the user identity is detected; and

a transmission module to send the identifier to the second node to enable the second node to obtain replacement of a temporary network address allocated to the second node with one of the one or more permanent network addresses.

2. The system of claim 1, wherein the first node comprises a directory service server.

3. The system of claim 1, further comprising:

the storage unit housed in the first node or in a third node.

21. The system of claim 1, further comprising:

another node to receive a release request from the second node to release a temporary network address allocated to the second node, wherein the other node is to receive an allocation request from the second node to allocate at least one of the one or more permanent network addresses previously assigned to the user identity, and wherein the allocation request includes the identifier.

22. The system of claim 21, wherein the other node comprises a Dynamic Host Configuration Protocol (DHCP) server.

23. The system of claim 21, wherein the other node further comprises:

an allocation module to allocate at the least one of the one or more permanent network addresses to the second node as a replacement for the temporary network address.

4-6. -6. (canceled)

7. A processor-implemented method to execute on one or more processors that perform the method, comprising:

assigning a permanent network address to a user identity;

detecting access to a network by a node associated with the user identity;

generating an identifier associated with the user identity; and

sending the identifier to the node to enable the node to obtain replacement of a temporary network address allocated to the node with the permanent network address.

8. The method of claim 7, wherein the detecting comprises:

authenticating the user identity.

9. The method of claim 8, wherein the authenticating comprises:

determining that log-in credentials received from the node are associated with the user identity.

10. The method of claim 7, wherein the generating comprises:

generating the identifier as a random identifier.

11. The method of claim 7, further comprising:

receiving an address mapping request from an address management server, the request including the identifier.

12. The method of claim 7, further comprising:

sending an address mapping list including the permanent network address to an address management server in response to receiving a request from the address management server, the request including the identifier.

13. The method of claim 7, wherein the sending comprises:

sending the address mapping list from a directory service.

24. The method of claim 7, further comprising:

receiving a release request from the node to release the temporary network address allocated to the node; and

allocating the permanent network address to the node as a replacement for the temporary network address.

25. The method of claim 7, further comprising:

receiving an allocation request from the node to allocate the permanent network address previously assigned to the user identity, wherein the request includes an identifier generated in association with the node and the user identity.

26. The method of claim 25, wherein the allocation request is received from the node comprising one of a physical machine or a virtual machine.

27. The method of claim 7, wherein the identifier comprises a randomly-generated identifier generated by a directory service.

28. The method of claim 7, further comprising:

transmitting an address mapping request to a directory service, the request including the identifier.

29. The method of claim 7, further comprising:

receiving an address mapping list including the permanent network address from a directory service.

30. The method of claim 29, wherein the address mapping list comprises:

multiple permanently-assigned network addresses associated with the user identity, including the permanent network address.

14-20. -20. (canceled)
