Multicast is almost mandatory in multinode environments (for instance sessions replication in java apps servers) and in some common caches replicators as Terracotta.
I want to use digital ocean as a backup cloud environment, but need multi-casting support at the private network level, for clustering of servers. Without this ability I cannot cluster.
For Hazelcast and other data grid solutions multicast is much more preferable to tcp as it allows dynamic cluster node discovery, with tcp you need to supply a list of well know addresses which is hard without fixed ip addresses.
I've seen people using Zookeeper to work around this but it is extra faff.
I think it does not Support. I just checked with them

Is there any instructions, to enable multicast manually?

Multicast is also needed to use CARP (Common Address Redundancy Protocol) with FreeBSD … or of course Linux.

Elastic Search needs multicast in order to autodiscover nodes in the cluster.

I'll have to find a new provider if multicast still isn't supported. I'm completely dependent on it for service discovery.
