On Linux if you have iptables and ipset installed you can put the contents of the above gist into a file (say /var/tmp/facebook-nets) and then you can do the following;

# ipset create block-facebook-nets hash:net
# for net in $(cat /var/tmp/facebook-nets) ; do ipset add block-facebook-nets $net ; done

NOTE: you may get warnings / errors that some of the nets are already included, you can ignore these types of errors

# iptables -A OUTPUT -m set --match-set block-facebook-ips dst -j REJECT

NOTE: this blocks all outbound traffic from your machine to facebook (i.e. your browser trying to load facebook pages or widgets / sharing tools)

# iptables -L OUTPUT -nv
Chain OUTPUT (policy ACCEPT 1212 packets, 145K bytes)
 pkts bytes target     prot opt in     out     source               destination
   0     0   REJECT    all  --  *      *       0.0.0.0/0            0.0.0.0/0            match-set block-facebook-ips dst reject-with icmp-port-unreachable

You can also block packets coming in from facebook's networks but this would almost never happen without an outbound connection first.

There is complete list of facebook ips in CIDR format :

If you are like me and found this trying to filter out FB from Google Analytics this will do the trick.

https://gist.github.com/weber93/2decc1b2f255978dd66e7598f8553327

This do the trick (from stackoverflow)
whois -h whois.radb.net -- '-i origin AS32934' | grep ^route

I tested, it also blocks instagram

Please add 31.13.114.65/24 to the list.

@Corepany I wouldn't use that command as for some reason not all Facebook servers are returned through this :/. For example 31.13.113.90 ( from the Facebook Ireland datacenter ) is not included in this. So any whitelist will be incorrect.

@peterver Not sure whether it did back in February, but the whois output includes 31.13.96.0/19 now, so at least 31.13.113.90 is also covered. More importantly, that output also includes IPv6, which the list here sorely lacks.

31.13.114.65/24

you can try this in case you have windows
block_facebook

No need for this at the moment, since FB is down anyway ;)

This tool will find all sorts of network ranges owned by whichever company you want: https://github.com/NetSPI/NetblockTool
