Hi,

David said this better than I was about to:

How does that make things better (or stop them getting worse)?

Since the IETF is deemed to have change control over the DNS, it means folks 
who are trying to develop/operate DNS implementations have one place to go to 
instead of trying to figure out through rumor, lore, and oral tradition what 
the rules are.

(Note: I'm making a distinction between efforts like .internal that assume the 
use the DNS protocol from the various non-DNS efforts like GNS)

I’ll also note that we can sidestep the issues around the SUDN entirely:

"The IAB/IETF did not voice any objection to the ICANN Board permanently 
reserving a top-level string according to the ICANN Board minutes for the 
meeting dated 24 July 2024.  The expectation of the IETF Chair and the IAB 
Chair was that the string be reserved within the IANA-managed reserved domain 
registry rather than the special-use domain names registry.  There is an editor 
note in Section 4 of draft-davies-internal-tld-03 which states that: "It not 
yet decided if the "internal" top-level domain should be added to the list of 
special-use domain names".  The positions taken are somewhat contradictory.

The Liaison correspondence between IETF and ICANN regarding the .internal 
issue, including a link to the original letter from the ICANN CEO, is at 
https://datatracker.ietf.org/liaison/1706/.  Taking the IAB/IETF advice there 
allows for clear meaning to the reservation of the string, in both the IETF and 
ICANN contexts. In the IANA “reserved” registry, it's clearly under the control 
of IANA and separate to the SUDN registry.

(The reserved domains registry is not in the usual place because it’s not an 
IETF registry; as the liaison statement notes, it’s an IANA registry and can be 
found at https://www.iana.org/domains/reserved. The IETF wouldn’t be directing 
the reservation of .internal in an IETF registry but providing information that 
IANA had reserved it, in an Informational RFC.)
