Hi, There has been a lot of talk in this thread about DNS. I want a solution that works without DNS. If one uses SIP or RTSP to establish a media pat using DCCP. In most cases one do include the explicit IP address rather than the FQDN. Thus no DNS queries etc. I think something that makes

Hi, one question we really need to answer is whether we want to go through the pains of specifying UDP encapsulations for all our transport protocols. We have on the table: * draft-phelan-dccp-natencap for DCCP * draft-tuexen-sctp-udp-encaps for SCTP * JDR's recent

Hi Lars, I sympathize with your concern for each transport inventing its own UDP encap solution. However, I don't think that that IP/UDP/IP/DCCP[SCTP][whatever] works well. What is in the inner IP addresses? They're not useful at all. They could start out the same as the outer addresses, but
