Facebook Servers Pinging Home Users?

I’ve been playing around with splunk lately, and one thing I’ve noticed is that I am getting a lot of pings from a certain range of IPs. I block inbound ping at my firewall, but this was so persistent I got a little curious. Here’s the log exerpt that piqued my interest:



Jan 23 2012 22:02:17 brt-fw-01 : %ASA-3-313001: Denied ICMP type=8, code=0 from 69.63.186.228 on interface outside
Jan 23 2012 22:02:17 brt-fw-01 : %ASA-3-313001: Denied ICMP type=8, code=0 from 69.63.186.228 on interface outside
Jan 23 2012 22:02:16 brt-fw-01 : %ASA-3-313001: Denied ICMP type=8, code=0 from 69.63.186.228 on interface outside
Jan 23 2012 21:55:05 brt-fw-01 : %ASA-3-313001: Denied ICMP type=8, code=0 from 69.171.228.232 on interface outside
Jan 23 2012 21:55:05 brt-fw-01 : %ASA-3-313001: Denied ICMP type=8, code=0 from 69.171.228.232 on interface outside
Jan 23 2012 21:55:04 brt-fw-01 : %ASA-3-313001: Denied ICMP type=8, code=0 from 69.171.228.232 on interface outside
Jan 23 2012 21:45:58 brt-fw-01 : %ASA-3-313001: Denied ICMP type=8, code=0 from 69.63.179.30 on interface outside

That’s the trimmed output, but you can see a bigger set of logs if you’re interested.

So just who are these persistent pingers?

As you can see, both ranges are owned by Facebook. So the question of the day… Why is Facebook ping scanning me?!? Get your guesses in now, because I’m going to email their abuse address and see what they say. 😉
