Configuration Presets

You can either use a configuration preset or create your own configuration. It is possible to replay the original traffic over various different protocols with different client behaviours simultaneously. For example, you can split your traffic into 60 % UDP, 20 % DoT and 20 % DoH.

There are the following predefined use-cases for simplicity of use without the need to create a configuration file. You can pass these values instead of filepath to -c/--config option of replay.py utility.

• udp
  • 100 % DNS-over-UDP clients
• tcp
  • 100 % well-behaved DNS-over-TCP clients
• dot
  • 100 % well-behaved DNS-over-TLS clients using TLS Session Resumption
• doh
  • 50 % well-behaved DNS-over-HTTPS GET clients using TLS Session Resumption
  • 50 % well-behaved DNS-over-HTTPS POST clients using TLS Session Resumption
• mixed
  • 60 % DNS-over-UDP clients
  • 5 % well-behaved DNS-over-TCP clients
  • 5 % aggressive DNS-over-TCP clients
  • 10 % well-behaved DNS-over-TLS clients using TLS Session Resumption
  • 5 % well-behaved DNS-over-TLS clients without TLS Session Resumption
  • 10 % well-behaved DNS-over-HTTPS GET clients using TLS Session Resumption
  • 5 % well-behaved DNS-over-TLS POST clients using TLS Session Resumption
