1. An Internet Protocol Address Management (IPAM) system for managing an Internet Protocol (IP) address space of an enterprise network for an enterprise, comprising: a processor configured to: determine that a network address associated with a host device on the enterprise network is an IP version 6 (IPv6) network address; determine a Media Access Control (MAC) address for the host device on the enterprise network based on the IPv6 network address; perform a network communication with a MAC registry via an Internet communication to perform a MAC address lookup in a MAC registry to automatically determine a vendor name associated with the MAC address using a MAC lookup module; associate a first name with a first substring of the IPv6 network address of the host device; associate a second name with a second substring of the IPv6 network address of the host device; associate the vendor name with a third substring of the IPv6 network address of the host device, wherein the vendor name was determined based on the MAC address lookup in the MAC registry; and store the first name, the second name, and the vendor name in association with the IPv6 network address in the IPAM system for managing the IP address space for the enterprise network; and a memory coupled to the processor and configured to provide the processor with instructions.
