This is possible, you can have two or more isolated clusters in one network
or even on one physical box. This is achieved with a proper discovery
configuration. Please refer to one of the previous discussions for various
solutions [1].

Multicast IP range is 224.0.0.0 through 239.255.255.255 (some of them
already assigned) [1] and Ignite doesn't introduce any additional
limitations here. You should use unassigned addresses that are not used in
your network for any other purposes. Each cluster should use the unique
address.

Hi,

I'm not sure I understand your concern. You should assign a separate
multicast group for each Ignite cluster  and make sure that none of these
groups are used by other applications. This will isolate different services
from each other.

Makes sense?

You can use any multicast address that is available for you. Ignite doesn't
have any limitations.

Hi,

This is just an address of a specific multicast group. Every node that is a
part of this multicast group will be able to see each other and won't be
able to see the nodes that have different multicast group being set in their
TcpDiscoveryMulticastIpFinder configuration.

Regards,
Denis
