This is really close, but not quite right.

This regex is matching commented zone directives and if the comment is found after the real one is overwriting good answers for bad ones.

I need to avoid commented stanzas. Since commented stanzas include comment characters prior to the match of zone, I think I need a way to ensure that matches on the word zone. Am I thinking correctly?

By "commented," do you mean those containing either the "//" or "#" characters? Do you want to avoid all zone stanzas that contain those characters and use only those zone stanzas that don't contain those comment characters, i.e., "//" and "#"?

[ranceh]

right, I need to avoid stanzas that begin with the // or #

Try the following modified regex in the subroutine:

/(?<!#|\/)\s*zone\s+"([^"]+)".+?masters\s+{[\s#\/]*([a-zA-Z0-9.-]+)[\s
+#\/;]*}/sg

Added:

(?<!#|\/)\s*zone
  ^  ^    ^
  |  |    |
  |  |    + - 0+ whitespaces
  |  + - Match "zone" and 0+ whitespaces that are not preceded by an "
+#" or "/"
  + - Negative lookbehind
