Everything old is new again. I have this brand new earth shattering idea to suspend a seat on a frame between two wheels, attach a sprocket to the rear wheel, and by means of a chain between the rear sprocket and a rotating pedal assembly allow a user to sit on and propel the device forwards. I call it a biwheelmobile. :-) > The use case is to support multiple records on a node where you would > have previously used a CNAME.

Let me know if decide to write this up and you want input on our (DNS Made Easy) implementation. I suspect that our implementation is different from yours. -DMM > Sincerely, > Anthony Eden > > > On Fri, Apr 4, 2014 at 11:23 AM, Marco Davids (SIDN) > <[email protected] <mailto:[email protected]>> wrote: > > > > On 04-04-14 11:20, Stephane Bortzmeyer wrote: > > > > > > > http://blog.cloudflare.com/introducing-cname-flattening-rfc-compliant-cnames-at-a-domains-root > > > > Funny idea > > Indeed. > > Until you want to use DNSSEC. > > -- > Marco > > > _______________________________________________ > dns-operations mailing list > [email protected] > <mailto:[email protected]> > https://lists.dns-oarc.net/mailman/listinfo/dns-operations > dns-jobs <https://lists.dns-oarc.net/mailman/listinfo/dns-operations > dns-jobs> mailing list > https://lists.dns-oarc.net/mailman/listinfo/dns-jobs > > > > > -- > DNSimple.com > http://dnsimple.com/ > Twitter: @dnsimple > > > _______________________________________________ > dns-operations mailing list > [email protected] > https://lists.dns-oarc.net/mailman/listinfo/dns-operations > dns-jobs mailing list > https://lists.dns-oarc.net/mailman/listinfo/dns-jobs >
