Where is the addition of address/mx records at the zone apex prohibited?
B.T.W. Address and mx records are very common, just their *use* at
the apex of a TLD is or should be uncommon.
There is also no such thing as "in-bailiwick glue for the TLDâs DNS
servers". The root zone contains glue for TLDs. No TLD zone
contains glue for TLDs.
The agreement explicitly outlaws the use of wildcard records. It
would not have been hard to explicitly outlaw the addition of address
and MX records at the zones apex. One can only think that the loose
wording here was done to explictly allow address and MX records at
the apex of a TLD.
22.214.171.124 TLD Zone Contents
ICANN receives a number of inquiries about use of various
record types in a registry zone, as entities contemplate
different business and technical models. Permissible zone
contents for a TLD zone are:
* Apex SOA record.
* Apex NS records and in-bailiwick glue for the TLDâs
* NS records and in-bailiwick glue for DNS servers of
registered names in the TLD.
* DS records for registered names in the TLD.
* Records associated with signing the TLD zone (i.e.,
RRSIG, DNSKEY, NSEC, and NSEC3).
An applicant wishing to place any other record types into
its TLD zone should describe in detail its proposal in the
registry services section of the application. This will be
evaluated and could result in an extended evaluation to
determine whether the service would create a risk of a
meaningful adverse impact on security or stability of the
DNS. Applicants should be aware that a service based on
use of less-common DNS resource records in the TLD zone,
even if approved in the registry services review, might not
work as intended for all users due to lack of application
