Hi guys, How to resolve this strange IP pblm 8 years 4 months ago #26924

one IP is pulling out an udp connection from my server. When I check with the whois or some lookups it was an IP theat was registered for "IANA Special Use" I wanna check which IP was that, 227.2.3.7. I wanna know whether it was an ordinary update IP for any software update. How can I figure it out..
I also wanna Know how my application is making that connection and had to prevent it if suspicious. How can I Find it out.

IP 227.2.3.7 is a class D address since it is within the 224.0.0.0 to 239.255.255.255 range. It is reserved for multi-casting, not for assigning to hosts. May I ask was it the source or destination IP address on the traffic your receiving?
