The Dynamic Host Configuration Protocol for IPv4 (DHCPv4) has been extended with a Leasequery capability that allows a requestor to request information about DHCPv4 bindings (RFC 4388). That mechanism is limited to queries for individual bindings. In some situations, individual binding queries may not be efficient, or even possible. In addition, continuous update of an external requestor with Leas…
The Port Control Protocol (PCP) anycast addresses enable PCP clients to transmit signaling messages to their closest PCP-aware on-path NAT, firewall, or other middlebox without having to learn the IP address of that middlebox via some external channel. This document establishes one well-known IPv4 address and one well-known IPv6 address to be used as PCP anycast addresses.
Multi-Topology Extension for the Optimized Link State Routing Protocol Version 2 (OLSRv2)
This specification describes an extension to the Optimized Link State Routing Protocol version 2 (OLSRv2) to support multiple routing topologies, while retaining interoperability with OLSRv2 routers that do not implement this extension. This specification updates RFCs 7188 and 7631 by modifying and extending TLV registries and descriptions.
Security and Privacy Considerations for IPv6 Address Generation Mechanisms
This document discusses privacy and security considerations for several IPv6 address generation mechanisms, both standardized and non-standardized. It evaluates how different mechanisms mitigate different threats and the trade-offs that implementors, developers, and users face in choosing different addresses or address generation mechanisms.
DNS Root Name Service Protocol and Deployment Requirements
The DNS root name service is a critical part of the Internet architecture. The protocol and deployment requirements for the DNS root name service are defined in this document. Operational requirements are out of scope.
The DNS is defined in literally dozens of different RFCs. The terminology used by implementers and developers of DNS protocols, and by operators of DNS systems, has sometimes changed in the decades since the DNS was first defined. This document gives current definitions for many of the terms used in the DNS in a single document.
Registries for the One-Way Active Measurement Protocol (OWAMP)
This memo describes the registries for OWAMP -- the One-Way Active Measurement Protocol. The registries allow assignment of Mode bit positions and OWAMP Command numbers. Per this memo, IANA has established the registries for new features, called the OWAMP-Modes registry and the OWAMP Control Command Number registry. This memo updates RFC 4656.
IKEv2-Derived Shared Secret Key for the One-Way Active Measurement Protocol (OWAMP) and Two-Way Active Measurement Protocol (TWAMP)
The One-Way Active Measurement Protocol (OWAMP) and Two-Way Active Measurement Protocol (TWAMP) security mechanisms require that both the client and server endpoints possess a shared secret. This document describes the use of keys derived from an IKEv2 security association (SA) as the shared key in OWAMP or TWAMP. If the shared key can be derived from the IKEv2 SA, OWAMP or TWAMP can support certi…
Global Table Multicast with BGP Multicast VPN (BGP-MVPN) Procedures
RFCs 6513, 6514, and others describe protocols and procedures that a Service Provider (SP) may deploy in order to offer Multicast Virtual Private Network (Multicast VPN or MVPN) service to its customers. Some of these procedures use BGP to distribute VPN-specific multicast routing information across a backbone network. With a small number of relatively minor modifications, the same BGP procedures …

Congestion Exposure (ConEx) Concepts, Abstract Mechanism, and Requirements
This document describes an abstract mechanism by which senders inform the network about the congestion recently encountered by packets in the same flow. Today, network elements at any layer may signal congestion to the receiver by dropping packets or by Explicit Congestion Notification (ECN) markings, and the receiver passes this information back to the sender in transport-layer feedback. The mech…
Domain Name Associations (DNA) in the Extensible Messaging and Presence Protocol (XMPP)
This document improves the security of the Extensible Messaging and Presence Protocol (XMPP) in two ways. First, it specifies how to establish a strong association between a domain name and an XML stream, using the concept of "prooftypes". Second, it describes how to securely delegate a service domain name (e.g., example.com) to a target server hostname (e.g., hosting.example.net); this is especia…
Experience has shown that it is difficult to deploy proper PKIX certificates for Transport Layer Security (TLS) in multi-tenanted environments. As a result, domains hosted in such environments often deploy applications using certificates that identify the hosting service, not the hosted domain. Such deployments force end users and peer services to accept a certificate with an improper identifier, …
Captive-Portal Identification Using DHCP or Router Advertisements (RAs)
In many environments offering short-term or temporary Internet access (such as coffee shops), it is common to start new connections in a captive-portal mode. This highly restricts what the customer can do until the customer has authenticated. This document describes a DHCP option (and a Router Advertisement (RA) extension) to inform clients that they are behind some sort of captive-portal device a…
Requirements for Very Fast Setup of GMPLS Label Switched Paths (LSPs)
Establishment and control of Label Switch Paths (LSPs) have become mainstream tools of commercial and government network providers. One of the elements of further evolving such networks is scaling their performance in terms of LSP bandwidth and traffic loads, LSP intensity (e.g., rate of LSP creation, deletion, and modification), LSP set up delay, quality-of-service differentiation, and different …
Using a Generic Associated Channel Label as a Virtual Circuit Connectivity Verification Channel Indicator
The Virtual Circuit Connectivity Verification (VCCV) protocol specified in RFC 5085 provides a control channel (CC) that is associated with a pseudowire (PW). This document specifies an additional VCCV control channel type to be used with pseudowires that do not use the PW Control Word and that are carried over an MPLS network. This new VCCV CC type uses the Generic Associated Channel Label define…
