[arin-announce] ARIN DNSSEC Changes on 27 April

ARIN is proud to announce that on 27 April, we will place Delegation 
Signer (DS) records into in-addr.arpa and ip6.arpa. At that point, 
DNSSEC validation will occur from the root down if you properly set up 
your DNSSEC-aware recursive resolver. ARIN's DNSSEC initiative will be 
considered complete once these DS records are in place.

For most DNSSEC-aware recursive resolver operators, nothing needs to be 
done for this change to be in effect as long as you have configured your 
DNSSEC-aware server to use ICANN's Key Signing Key (KSK) for the root 
zone. For those who have used ARIN's trust anchors (in place since 2 
July 2009) to take advantage of DNSSEC before the root or in-addr.arpa 
was signed, you MUST remove them within the next two months of this 
date. Otherwise, DNSSEC validation may fail due to a KSK change. 
Additionally, ARIN will also coordinate with Internet Systems 
Consortium, Inc. (ISC) to remove ARIN's delegations from their DNSSEC 
Lookaside Validation (DLV) registry after setting up these records in 
in-addr.arpa and ip6.arpa.

The DS records will remain the same as the current trust anchor for the 
next two months. After that time, ARIN will begin rolling a KSK for its 
authoritative zones, which will cause any DNSSEC-enabled resolvers that 
use ARIN's statically configured trust anchors to fail.

As always, ARIN welcomes community feedback regarding DNSSEC. Subscribe 
and participate on the arin-tech-discuss at arin.net mailing list if you 
have questions or comments.
