+# Note that it is presently the policy of IANA to assign a single well-known
+# port number for both TCP and UDP; hence, officially ports have two entries
+# even if the protocol doesn't support UDP operations.
+#
+# Updated from https://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml .
+#
+# New ports will be added on request if they have been officially assigned
