How should I choose an IPv4 multicast address for my application\'s use? I may need more than one (a whole range perhaps ultimately) but just want to avoid conflicts with ot
If it is just for internal use then why not just externalize the address range as configuration and continue to use internal use.
The Internet Assigned Numbers Authority is responsible for assigning IP addresses. They do not allocate to ISPs or individuals but on they have information where to get numbers allocated depending on your region.
