Strange IP showing up on network.

They are IP's that are used for local routing, see http://en.wikipedia.org/wiki/Multicast_address

Our IP range is in the 10.0.0.0 area. IP Addresses like 239.255.255.250 & 239.255.100.100 along with 224.1.1.1 & 224.0.0.2 (and many other 224.X.X.X) IPs keep showing up in my DNS records on my computer. 

When I open a command prompt and type arp -a (lists my DNS cache IIRC), these IPs show up.

None respond when I ping them except for 239.255.100.100 but it responds from one of our 10.0.0.X IPs which is a Color Printer. 

Just thought I'd ask here to see if anyone knows what these are about as we have no devices with these IPs.

Do you own any game servers or anything?
