DNS-Betreiber aufgepasst: DNSSEC Update 11.10.2018

Technik
1

On 11 October 2018, ICANN will change or „roll over“ the DNSSEC key
signing key (KSK) of the DNS root zone. Based on information from your
network received at the DNS root name servers [1], we believe that
there may be at least one recursive resolver (also referred to as a
recursive name server or caching name server) with DNSSEC validation
enabled in AS201701 that is unprepared for the KSK rollover. If that
resolver is not updated before 11 October 2018, users of that resolver
will not be able to resolve any DNS queries, resulting in an outage
for them.

To repeat this important point: any DNS resolvers on your network with
DNSSEC validation enabled that are not properly updated to use the new
KSK will fail on 11 October 2018 or shortly thereafter.

For more information on how to check whether a resolver you operate
has the new KSK, see:
https://www.icann.org/dns-resolvers-checking-current-trust-anchors

For more information on how to update your resolver to use the new
KSK, see:
Updating of DNS Validating Resolvers with the Latest Trust Anchor - ICANN

In advance of the rollover, we are running a short survey of network
operators who we believe are running one or more validating DNS
resolvers that we believe may be unprepared for the rollover. Your
participation in the survey will be valuable to the entire operations
community.

Please take the survey about your preparedness for the root KSK
rollover:

https://www.research.net/r/KSKRolloverPreparedness?ASnumber=201701

We will be accepting responses for 14 days, ending on 4 September 2018.

For more information about the root KSK rollover project, see:
Root Zone KSK Rollover - ICANN

If you have questions about the rollover or this survey, please send
email to globalsupport@icann.org with „KSK Rollover“ in the subject
line.

[1] One or more resolvers on your network appear to be configured to
send queries to the root name servers to report their DNSSEC trust
anchor configuration. Please see RFC 8145
(https://www.rfc-editor.org/rfc/rfc8145.txt) for more information
about this reporting mechanism.
