DNS Analysis Report June 2024

Source: Vercara
Release Date: June 2024

 

June 2024 saw over 3.73 trillion DNS queries, reflecting a 4.12% decrease compared to May 2024, with a daily query average of over 124.65 billion queries.

 

This decrease is anticipated due to June having one less day than May. When comparing the overall numbers from June to May, every DNS record type experienced a decrease. However, the percentages relative to the total number of queries remained almost unchanged.

 

Notably, June saw a decrease in NX Domain response codes, but June also saw an increase in the Refused and Form Error response codes. June also saw a significant rise in the number of DDoS attacks against the UltraDNS platform, with 528, marking a 236.31% increase when compared to the prior month. Despite the increase in frequency, these DDoS attacks were very small in scale.

 

Stats at a glance.

 

  • Total Authoritative Queries: 3.73 trillion
  • Percentage of queries using IPV6: 24%
  • Percentage of queries for AAAA (IPV6) records: 18.09%
  • Percentage of NOERR query answers: 77.11%
