I'am confused about multicast in a private subnet.

Currently I have the following situation:

subnet 10.0.0.0/24
NAT router 10.0.0.1 (ubuntu)
pc1 10.0.0.2
pc2 10.0.0.3

pc1 and pc2 using the multicast address 228.0.0.4. Does this mean its only for this network? Are the pc still "protected" by the NAT?

you are using global multicast range (internet wide ) of address.So 228.0.0.4 may not be only for this network. Multicast and NAT are not interrelated.

  • what you mean with "may not be only for this network"? I dont own 228.0.0.4 but it is working (in private subnet). I want to understand why its working. – wot-stefan Nov 17 '16 at 16:15
  • If i send a UDP package to all members of 228.0.0.4. Does the router route it to the public internet? – wot-stefan Nov 17 '16 at 22:52
