Subject: Re: Class D addresses? was: Redploying most of 127/8 as unicast public Date: Sat, Nov 20, 2021 at 11:51:24AM -0800 Quoting William Herrin (bill@herrin.us):
Multicast is not the same as broadcast and yes, it's a thing. Mainly it's a thing confined to the local broadcast domain but in that scope it's quite widely used.
All the heavy lifting in video production via IP is done over multicast. Mostly, it is internal to one organisation, and the 239/8 (RFC2365) block is being used, but routing multi-gbit RTP flows over multicast is a thing where I work. -- Måns Nilsson primary/secondary/besserwisser/machina MN-1334-RIPE SA0XLR +46 705 989668 YOU!!
