 #1

  • Subject changed from Unbound ignored host overrides with "0" (zero) as hostname. to Unbound omits 0 from host overrides where "0" (zero) is hostname.
  • Status changed from New to Resolved
  • Affected Version changed from 2.2.1 to All

It was omitting the 0 because that if check was wrong for values of 0. fixed, along with the same issue where alias name is 0.
