We use FreeBSD-12 and Bind-9.11.6. We have DNSSEC enabled for some of our domains. I wish to verify the signature expiry date for these zones. I cannot seem to locate any information on exactly how this is done. Can someone provide me with this information?
drill -D [domain]
should return the RRSIG value for your domain (if DNSSEC is working) with the expiration as well
