  • Program: dnsdist
  • Issue type: Bug report

Short description

dnsdist copies the QNAME as sent by the client into the buffer used for generating statistics. As a result a client sending 0x20 queries generates odd output in topQueries().


  • Operating system: Ubuntu 16.04
  • Software version: 1.1.0
  • Software source: pdns repo

Other information
