Enabling internet protocol carrier peering to foreign network domains

A system comprising:

• a processor;
• and
• a memory that stores computer-executable instructions that, in response to being executed by the processor, cause the processor to perform operations comprising:
• identifying a plurality of numbering plan area identifiers corresponding to a receiving carrier network, wherein the system is associated with an originating carrier network,
• accessing, based on the plurality of numbering plan area identifiers, a plurality of numbering plan area zone file records stored on a private enabled telephone number mapping server associated with the originating carrier network,
• creating a single instance of a name authority pointer record placeholder within each of the plurality of numbering plan area zone file records stored on the private enabled telephone number mapping server, and
• removing, from within each of the plurality of numbering plan area zone file records, a plurality of telephone numbers stored as name authority pointer records corresponding to one of the plurality of numbering plan area identifiers.
