IPv6 addresses improperly encoded in carbon metrics #5538

  • Program: dnsdist
  • Issue type: Bug report

Short description

When logging to carbon, IPv6 addresses are enclosed in square brackets ([]) within metric names. Square brackets have special meaning to many storage engines and frontends.


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

Steps to reproduce

  1. Configure dnsdist with an IPv6 interface and logging to a carbon server
  2. Observe the metric names within your carbon instance
  3. IPv4 addresses are encoded as 10_0_0_1:53_tcp, IPv6 addresses are encoded as [2001:db8::1]:53_tcp

Expected behaviour

A recommended encoding would be 2001:db8::1_53_tcp. It is really a toss-up on the colons becoming ambiguous or breaking with the v4 encoding.
