Weird subnet mask

I dont know why some of my programs want to connect to a subnet with the address:

230.255.255.250

anyone got any ideas
 
That is actually a multicast address. A multicast address is used to address a group of computers joined to the multicast group.

Interesting...which programs specifically are trying to communicate via this addy?
 
You can take a look at this site http://www.iana.org/assignments/multicast-addresses that has all the multicast addresses listed and who they are registered to. That address isn't reserved for anything special like these:

224.0.0.1 - all machines on the subnet
224.0.0.2 - all routers on the subnet
224.0.0.5 - OSPF routers on the subnet
224.0.0.6 - OSPF v2 designated routers on the subnet
224.0.0.9 - RIP v2
224.0.0.12- DHCP server/relay
224.0.1.1 - NTP

Is your machine directly connected to the internet without going through another networking device like a router? I'd watch the traffic and see if it comes the other way. If you see that address listed as a source address and not a destination, then somebody is spoofing off that address.
