Introduction   This memo updates the IANA registry rules for the Telephony Routing   over IP (TRIP) protocol, by no longer requiring that postal addresses   be included in contact information.  No use for the addresses is   identified, and omitting this information provides a privacy benefit.   This memo updatesRFC 3219.2.  IANA Considerations   This memo updates the registration rules [RFC8126] for TRIP   Attributes ([RFC3219], Section 13.2) and TRIP IP Telephony   Administrative Domain (ITAD) Numbers ([RFC3219], Section 13.5) as   follows.   The IETF no longer requires IANA to collect postal address   information when adding TRIP registry entries.  Additionally, IANA   has removed previously collected postal addresses from the   registries.3.  Security Considerations   No security impacts of this change have been identified.4.
