determining whether the particular IP address and the reference IP address have a same subnet allocation; and

responsive to a determination that the particular IP address and the reference IP address have the same subnet allocation, determining that the ownership assignment of the particular IP address is the same as the ownership assignment of the reference IP address.

2 . The method of claim 1 , further comprising:

responsive to determining the ownership assignment of the particular IP address, determining that a computer device of the multiple computer devices is assigned to a same team of the organization as the reference IP address.

converting each of the IP addresses into a binary representation;

concatenating the binary representation into a binary string; and

converting the binary string into the numerical value.

6 . The method of claim 1 ,

wherein the subnet allocation database stores ownership information for the IP addresses associated with the telecommunications network, and

wherein the subnet allocation is based on segments of the sequence of IP addresses assigned to the multiple teams.

7 . The method of claim 1 , wherein obtaining the subnet allocation for each IP address in the set of assigned IP addresses comprises:

determining a subnet mask for each of the IP addresses based on a network class or a network scheme associated with the telecommunications network; and

determining a subnet for each of the IP addresses based on the determined subnet mask and the respective IP address.

8 . The method of claim 1 , wherein determining whether the particular IP address and the reference IP address have the same subnet allocation comprises:

determining a subnet mask for the particular IP address based on a network class or a network scheme associated with the telecommunications network; and

determining a subnet for the particular IP address based on the determined subnet mask and the particular IP address.

9 . The method of claim 1 ,

wherein each IP address in the set of unassigned IP addresses is associated with at least one application programming interface of a respective computer device of the multiple computer devices on the telecommunications network.

10 . The method of claim 1 ,

wherein the multiple computer devices include electronic devices, server devices, and/or cloud servers in communication with the telecommunications network.

11 . A computer-implemented method for discovering ownership assignment of computer devices associated with a telecommunications network, the method comprising:

obtaining a set of unassigned internet protocol (IP) addresses for ownership assignment discovery,

wherein each IP address in the set of unassigned IP addresses is associated with a computer device of multiple computer devices on the telecommunications network, and

wherein each IP address in the set of unassigned IP addresses is from a sequence of IP addresses associated with an organization;

converting each IP address in the set of unassigned IP addresses into a numerical value representative of the respective IP address;

obtaining a set of assigned IP addresses from an assigned IP address database;
