Open a multicast UDP socket and bind it to the address and port (separated by spaces) and optionally a TTL value specified using

Subnets can either be single MAC, IPv4 or IPv6 addresses,
in which case a subnet consisting of only that single address is assumed,
or they can be a IPv4 or IPv6 network address with a prefixlength.
Shorthand notations are not supported.
For example, IPv4 subnets must be in a form like 192.168.1.0/24,
where 192.168.1.0 is the network address and 24 is the number of bits set in the netmask.
Note that subnets like 192.168.1.1/24 are invalid!
Read a networking HOWTO/FAQ/guide if you don't understand this.
IPv6 subnets are notated like fec0:0:0:1:0:0:0:0/64.
IPv6 subnets are notated like fec0:0:0:1::/64.
MAC addresses are notated like 0:1a:2b:3c:4d:5e.
