What is the best mask to use to allow computers to use the multicast IP address 220.127.116.11?
I've only seen IP addresses using the lower 8 bits, in my case I just see 22 and 251.
So my firewall uses an entry as follow:
-A INPUT -i eth1 -p udp -m udp -s 192.168.0.0/16 -d 18.104.22.168/24 -j ACCEPT
Now I have found other definitions that use a mask as small as 4 or 5 for the 22.214.171.124 address. What is the right mask according to the use of the 126.96.36.199 address scope definition?
