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