Farsight recently reported aggregate passive DNS statistics for all IANA top‐level domains (”TLDs”) for the period 2010‐2019 (see ”A Decade Of Passive DNS: A Snapshot of Top‐Level Domain Traffic).

That report described the TLDs’ statistics in summary form, but didn’t show how traffic changed longitudinally over that time period. This report fills that gap, providing year‐by‐year statistics for each TLD over the same period. It is based on the yearly MTBL files that Farsight itself uses for DNSDB and which are also provided to DNSDB Export (”DNSDB On Premises”) customers.
