dnsmeter is a tool for testing performance of a nameserver and the infrastructure around it. It generates DNS queries and sends them via UDP to a target nameserver and counts the answers.


  • payload can be given as a text file or a PCAP file
  • can automatically run different load steps, which can be given as a list or ranges
  • results per load step can be stored in a CSV file
  • sender addresses can be spoofed from a given network or from the addresses found in the PCAP file
  • answers are counted, even if source address is spoofed, if answers get routed back to the load generator
  • round-trip-times are measured (average, min, mix)
  • the amount of DNSSEC queries can be given as percentage of total traffic
  • optimized for high amount of packets, on an Intel(R) Xeon(R) CPU E5-2430 v2 @ 2.50GHz it can generate more than 900.000 packets per second
  • runs on Linux and FreeBSD
