Liaisons referred by this one Response to LS Regarding A Decentralized Architecture for Global IP Network Name Resolution System
LS/o on synchronization of Y.DNI-fr “Framework and Requirements of Decentralized Trustworthy Network Infrastructure” in Q2/13
LS on the ITU-T Y.2086 (formerly Y.DNI-fr) “Framework and Requirements of Decentralized Trustworthy Network Infrastructure”
The IETF would like to thank ITU-T SG13 for information about the consent of
Y.DNI-fr Framework and Requirements of Decentralized Trustworthy Network
Infrastructure.  The IETF’s response (
- 28 Nov 2010) to work on decentralized architecture for global IP network name
resolution system is still relevant:  From an IETF perspective the liaison from
28 Nov 2010 states:

  "The IETF maintains change control for the DNS protocol standards and the
    use of domain names in URIs, URNs, and other IETF protocols that depend
    on domain names.
    In particular, the DNS extensions working group (DNSEXT) is where work
    on the DNS protocol itself is done. That is also where expertise about the
    DNS exists, and where work that alters the architecture of host identifiers
    on the Internet should be done.

    Any protocol modification proposals can be brought to the IETF and are
    subject to its regular decision process."

Since the IETF’s liaison from 2010, the DNSEXT working group has concluded. 
DNS protocol work is now largely carried out in the Domain Name System
Operations (DNSOP) working group

Additionally, the IRTF has a group specifically chartered for research related
to Decentralized Internet Infrastructure (DINRG)

For BGP protocol work, see the BGP Enabled ServiceS (BESS) working group and the Inter-Domain Routing
Working Group (IDR)  For other
aspects of routing see the working groups in the IETF’s Routing Area  BGP deployment and operational
issues are discussed outside the IETF in various peering fora, IXP meetings,
and network operator user group meetings. The co-ordination and distribution of
Internet addresses and autonomous system numbers (ASNs) is handled by the 5
RIRs ( and the IANA (
Proposals to modify these arrangements should be submitted to the relevant
RIR’s policy development process. These procedures are open to all.

Global coordination of Internet domain names is carried out by ICANN and top-level domain (TLD) registries
( It is not an IETF responsibility. ICANN
and these TLD registries have their own policy-making procedures. These
procedures are also open to all.

The IETF looks forward to further engagement by ITU-T members in the IETF
process to advance work related to the protocol enhancements needed to support
a Decentralized Trustworthy Network Infrastructure.
