1. A method of operating one or more network components in a Fifth Generation (5G) telecommunications network that includes a domain name system (DNS), the method comprising:
querying the DNS for a global list of network repository functions (NRFs) in the 5G telecommunications network;
instantiating a new network function (NF) associated with a target geographic region;
iteratively querying one or more NRFs for lists of NFs associated with smaller geographic regions based on a preceding response,
wherein iteratively querying the one or more NRFs includes:
querying a global NRF based on the global list from the DNS;
receiving a regional list of regional NRFs based on the global NRF; and
registering the new NF with a regional NRF based on the regional list, wherein the regional NRF is associated with the target geographic region; and,
dynamically registering the new NF associated with the target geographic region based on one or more responses to the iterative queries of the one or more NRFs.
