I had a strange log in my firewall that, 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, 220.127.116.11. 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 and which of my application is making that connection and had to prevent it if suspicious. How can I Find it out.
