Invalid Top Level Domain Queries at the Root Level of the Domain Name System (R3)SAC045

Description:

ICANN should contact organizations that are associated with strings that are frequently queried at the root. Forewarn organizations who send many invalid queries for TLDs that are about to become valid, so they may mitigate or eliminate such queries before they induce referrals rather than NXDOMAIN responses from root serversTo address the DNSSEC problems identified in Section 6.4, the RSSAC recommends the Root Zone Management partners to increase the signature validity periods for signatures generated by both the KSK and the ZSK. KSK signature validity should be increased to at least 21 days. ZSK signature validity should be increased to at least 13 days.
