How do I display the contents of a .signed zone file in human-readable format?

BIND 9.9.0 introduced inline signing. BIND writes its backup signed zone file in raw format (this is the format in which the zone data is stored in working memory - it is faster to load/write the zone data in this format).

Use named-checkzone to read the file contents in the format that you're more used to seeing:

named-checkzone -D -f raw myzone.net myzone.net.db.signed

In the above example:

  • myzone.net is the name of the zone
  • myzone.net.db is the zone master file
  • myzone.net.db.signed is the preserved copy of the inline-signed zone
