My implementation of RFC 7344 is now in reasonably good shape, thanks to help from JP Mens. I have copied it into its own branch (based off today's master) at https://git.csx.cam.ac.uk/x/ucs/ipreg/bind9.git/log/refs/heads/u/fanf2/dnssec-cds There are three commits, two cleanup commits then one for dnssec-cds itself, including documentation and tests. I'll send the patches to this ticket as well. Tony. -- f.anthony.n.finch http://dotat.at/ - I xn--zr8h punycode East Sole, Lundy, Fastnet: Variable 4, becoming southeasterly 4 or 5 later.
