US Patent 11843540 System and method for deterministic hash addressing

Methods and apparatus are disclosed herein that enable an infrastructure service to route messages to various servers, even if the servers are not addressed by individual public network addresses. The infrastructure service distributed messages by processing a portion of the message through a hash function. By utilizing a reverse hash process, a server can determine a custom port number that will cause the hash algorithm to route a reply message directly to the selected server even when addressed to a communal address.
