                             Encrypted DNS
                      draft-btw-add-ipsecme-ike-02

Abstract

   This document specifies a new Internet Key Exchange Protocol Version
   2 (IKEv2) Configuration Payload Attribute Types for encrypted DNS
   with a focus on DNS-over-HTTPS (DoH), DNS-over-TLS (DoT), and DNS-
   over-QUIC (DoQ).

1.  Introduction

   This document specifies encrypted DNS configuration for an Internet
   Key Exchange Protocol Version 2 (IKEv2) [RFC7296] initiator,
   particularly the Authentication Domain Name (ADN) of DNS-over-HTTPS
   (DoH) [RFC8484], DNS-over-TLS (DoT) [RFC7858], or DNS-over-QUIC (DoQ)
   [I-D.ietf-dprive-dnsoquic].

   This document introduces new IKEv2 Configuration Payload Attribute
   Types (Section 4) for the support of DoT, DoH, and DoQ DNS servers.
   These attributes can be used to provision authentication domain
   names, a list of IP addresses, alternate port numbers, and a list of
   DoH URI Template.  The use of IKEv2 to provide these template is
   meant to allow deployments where customized DoH configuration (e.g.,
   per-subscriber or per-site) is required.

   Sample use cases are discussed in Section 3.  The Configuration
   Payload Attribute Types defined in this document are not specific to
   these deployments, but can also be used in other deployment contexts.
   It is out of the scope of this document to provide a comprehensive
