    abstract =  {A significant increase of periodic DS queries is observed at top level domain (TLD) DNS servers. Currently, almost all of periodic DS queries come from DNSSEC validators and are queries for unsigned delegations. The reason of the increase is low NCACHE TTL value and DS nonexistence. This phenomena is DNSSEC protocol and DNS parameter issue. DS queries will increase as DNSSEC validators will increase.},
