In your previous mail you wrote: Shouldn't be difficult. I'm not much into either technology, but since SCTP can be tunneled through UDP, it should be possible to retrofit SCTP adoption onto an existing DNS implementation. On an OS that provides SCTP natively, a module inserted between the DNS daemon and its UDP sockets may operate the UDP/SCTP conversion when the remote hosts support it. => I don't understand your argument: it seems to apply to UDP over SCTP but here we have SCTP over UDP. BTW the easiest way to convert DNS over UDP into DNS over SCTP is to use an ALG (application layer gateway) which in the DNS is known as a caching server (such servers are already used to provide IPv4/IPv6 transport conversion).
