I guess it's mostly true that DVMRP is no longer used for Internet-wide multicast routing. > I guess I've missed anything. Has multicast IP been > abandoned or obsoleted? No, only DVMRP. There were several issues with trying to maintain a global DVMRP-based multicast infrastructure. Multicast routing in the Internet is mostly based on PIM-SM (Protocol-Independent Multicast, Sparse Mode) these days. > Can anyone give me a hint about where and why this has happened? > What about the IETF broadcasts? Are they still delivered over > multicast? Yes, and I'm in Switzerland, listening to a radio station in Oregon over IP multicast right now, so the infrastructure is still there for people to use. However I don't know how wide the "reach" of Internet multicast is, in particular outside our education/research networking community (and even within that community, multicast is only available to a minority). Some broadband ISPs (at least here in Europe, but probably elsewhere as well) have started to distribute TV-over-ADSL using IP multicast. But I'm not sure whether they also provide their users with multicast connectivity to the rest of the Internet. Anyone knows? -- Simon. _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
