Abstract

Systems and methods for storing and managing pools of network addresses. An example method may comprise: receiving, by a processing device, a request for a network address to be associated with a network interface of a machine, wherein the machine is represented by one of: a virtual machine or a computer system; identifying a hierarchy of groups that include the machine; searching the hierarchy of groups to identify a group having an associated pool of network addresses; and selecting a network address from the pool of network addresses.

First claim

What is claimed is:

1 . The method comprising:
receiving, by a processing device, a request for a network address to be associated with a network interface of a machine, wherein the machine is represented by one of: a virtual machine or a computer system; identifying a hierarchy of groups that include the machine; searching the hierarchy of groups to identify a group having an associated pool of network addresses; and selecting a network address from the pool of network addresses.

2 . The method of claim 1 , wherein the hierarchy of groups comprises a group at a first level, a group at a second level and a plurality of machines, wherein the group at the first level includes the group at the second level and wherein the plurality of machines are associated with the group at the first level and the group at the second level.

3 . The method of claim 1 , wherein searching the group hierarchy comprises:
responsive to determining that the first machine group is not associated with a pool of network addresses, identifying a second machine group of the hierarchy of groups, wherein the first machine group is associated with a narrower scope than the second machine group.

4 . The method of claim 1 , wherein the pool of network addresses comprises at least one of: a range of media access control (MAC) addresses or a range of internet protocol (IP) addresses.

5 . The method of claim 1 , wherein the hierarchy of groups comprises at least three groups corresponding respectively to a data center, a cluster, and a pool of virtual machines.

6 . The method of claim 1 , wherein at least two groups of the hierarchy of groups are associated with different pools of network addresses.

7 . The method of claim 1 , further comprising: responsive to failing to select an available network address from the pool of network addresses aborting a creation of the virtual machine.

8 . The method of claim 1 , wherein the pool of network addresses may be associated with a user quota that restricts the amount of network addresses associated with a user.

9 . The system comprising:
a memory; a processing device communicably coupled to the memory, the processing device to:
receive, by a processing device, a request for a network address to be associated with a network interface of a machine, wherein the machine is represented by one of: a virtual machine or a computer system;
identify a hierarchy of groups that include the machine;
search the hierarchy of groups to identify a group having an associated pool of network addresses; and
select a network address from the pool of network addresses.

10 . The system of claim 9 , wherein the hierarchy of groups comprises a group at a first level, a group at a second level and a plurality of machines, wherein the group at the first level includes the group at the second level and wherein the plurality of machines are associated with the group at the first level and the group at the second level.

11 . The system of claim 9 , wherein search the group hierarchy comprises the processing device to:
identify a second machine group of the hierarchy of groups responsive to determining that the first machine group is not associated with a pool of network addresses, wherein the first machine group is associated with a narrower scope than the second machine group.

12 . The system of claim 9 , wherein the pool of network addresses comprises at least one of: a range of media access control (MAC) addresses or a range of internet protocol (IP) addresses.

13 . The system of claim 9 , wherein the hierarchy of groups comprises at least three groups corresponding respectively to a data center, a cluster, and a pool of virtual machines.

14 . The system of claim 9 , wherein at least two groups of the hierarchy of groups are associated with different pools of network addresses.

15 . The system of claim 9 , further comprising: responsive to failing to select an available network address aborting a creation of the virtual machine.

16 . The system of claim 9 , wherein the pool of network addresses may be associated with a user quota that restricts the amount of network addresses associated with a user.

17 . The non-transitory machine-readable storage medium storing instructions that cause a processing device to:
receive a request for a network address to be associated with a network interface of a machine, wherein the machine is represented by one of: a virtual machine or a computer system; identify a hierarchy of groups that include the machine; search the hierarchy of groups to identify a group having an associated pool of network addresses; and select a network address from the pool of network addresses.

18 . The non-transitory machine-readable storage medium of claim 17 , wherein the hierarchy of groups comprises a group at a first level, a group at a second level and a plurality of machines, wherein the group at the first level includes the group at the second level and wherein the plurality of machines are associated with the group at the first level and the group at the second level.

19 . The non-transitory machine-readable storage medium of claim 17 , wherein search the group hierarchy comprises instructions that further cause the processing device to:
identify a second machine group of the hierarchy of groups responsive to determining that the first machine group is not associated with a pool of network addresses, wherein the first machine group is associated with a narrower scope than the second machine group.

20 . The non-transitory machine-readable storage medium of claim 17 , wherein the pool of network addresses comprises at least one of: a range of media access control (MAC) addresses or a range of internet protocol (IP) addresses.
