You realise that two of them are signed now and the rest will be signed by 1st July?
Tony.
Yes, I realise that. I also realise that not all nameserver software can work as it work with DNSSEC. That is also a problem that has to be solved and for as far as I know all nameserver software we use support it or will support it in the future. As long as it is not supported by all nameserver software you can keep problems.
Nameservers that are not DNSSEC aware will not get responses that contain DNSSEC records unless a client explicitly requests a DNSSEC record type or make a * (ANY) request. There is no problem to solve. Just a lot of misunderstanding. That said the majority of nameservers on the planet are DNSSEC aware and will request the DNSSEC record to be returned. They will also fall back to plain DNS if middleware blocks the response. Mark -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: marka@isc.org
