Most vendors took out hardware multicast support and do it via recirculation these days. I'm more interested in other topics, this would likely be served by a CDN, and I'm curious if any CDNs have started placing gear behind CGN/LSN. I've also noticed some hotels and other 'guest net' folks capturing 4.2.2.1 and comparable open recursive name servers in-house. Two weeks ago I could ping 4.2.2.1 and get responses when TTL was set to 1 on my outgoing packets. - Jared
