4.  IANA Considerations

   Section 3.44 of this document suggests new text that would update the
   "Service Name and Transport Protocol Port Number Registry" for SCTP
   to be consistent with [RFC6335].

   IANA has confirmed that it is OK to make the proposed text change in
   an upcoming Standards Track document that will update [RFC4960].
   IANA is not asked to perform any other action, and this document does
   not request that IANA make a change to any registry.

5.  Security Considerations

   This document does not add any security considerations to those given
   in [RFC4960].
