There has been lots of discussion recently about DNSSEC issues, including whether it's desirable to sign internal zones. Independent of this most recent issue, a couple of weeks ago I did an informal survey, using DNSVIZ, of various TLDs. I found the following rather surprising results:
DNS-VIZ and "associates" TLD Signed? Comments -------------- ------- -------- dnsviz.net yes with 1 warning (!) iana.org yes icann.org yes isc.org yes arin.net yes ietf.org yes with many warnings & errors sandia.gov yes with many warnings & 1 error verisign.com yes dns-oarc.net yes Widely used and/or hi-tech TLD Signed? Comments -------------- ------- -------- google.com no gmail.com no youtube.com no apple.com no microsoft.com no amazon.com no walmart.com no outlook.com no 1e100.net no facebook.com no twitter.com no instagram.com no ibm.com no mozilla.org no wikipedia.org no redhat.com no w3c.org no bankofamerica.com no Does anybody have an explanation for why such big domains don't bother using DNSSEC? P.S. My opinion is that it probably worthwhile to sign internal zones, especially for organizations that are tempting targets and have many internal computers. -- Visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list ISC funds the development of this software with paid support subscriptions.
