Well what's making the connection? It looks like unencrypted http, if your
social security number and last known addresses are streaming by you should
be able to see them. It's a bit of a jump to say that FB (not that I'm
particularly fond of them) is spying on you from a single netstat command.

Even though TCP dump doesn't show it the ARP packets should have a
source mac address that is reachable on the link. I think the reply
is unicast to that mac address regardless of the IP in the request.
Otherwise the receiving station would have to do an arp request for
the source IP in the packet
I suppose so but BFD certainly has alot more moving parts then adding

You can break your blocks into /24's or smaller and readvertise them to
your upstreams. You can also modify local preference using community tags
with most upstreams. If you have tier 1 peerings you may be able to get
