Updated DNSSEC KSK Rollover Information

Posted: Wednesday, 02 June 2010

ARIN is notifying the community that it has just increased the KSK rollover period from one to two years.* We have increased the rollover period as a cautionary measure to mitigate additional load on authoritative nameservers.

For more information about ARIN's DNSSEC key maintenance procedure please see:

*We anticipate that our parent zone ( will be signed within two years and rollovers will then be transparent to the community, i.e.they would not involve manual reconfiguration at each key rollover event.
