where did these IP addresses come from?

guys what's a User Datagram Protocol anyway? how come 2 IP addresses are listed in my iptable and is being allowed connection, or i'm assuming ACCEPT is the same? i checked these on a web browser and they lead to sites i have never been to. although the sites that showed up seemed harmless, i really don't know why they are there...

answers anyone?

UDP is a connectionless protocol that, like TCP, runs on top of IP networks. Unlike TCP/IP, UDP/IP provides very few error recovery services, offering instead a direct way to send and receive datagrams over an IP network. It's used primarily for broadcasting messages over a network.

well why are there IP addresses being allowed connection when i didn't place them there?

Dunno. I haven't really worked with iptables. I only explained what UDP was.
Maybe you can post your file here and someone might have a explaination
