I am unable to verify this right now for the obvious reason, but facebook operates on ASN gAS32934[0] So you can ask https://www.radb.net/ https://www.radb.net

So you can ask https://www.radb.net/ https://www.radb.net/ for the IP addresses that are associated with this AS and, after a quick manual sanity check, insert it into the firewall of your choice. For example:
whois -h whois.radb.net '!gAS32934'| tr ' ' "\n" | sed 's/^/saddr /'| sed 's/$/ DROP;/'
