  Done, and used daily : https://github.com/smigniot/smigniot.github.io/blob/master/install_20210123_rules.sh https://github.com/smigniot/smigniot.github.io/blob/master/i... For the google part I had to recurse through the AS list first, and perform cidr merging

    Wouldn't ipset be easier to use and potentially faster?
    • dontchooseanick 6y ago
      Probably yes. It seems easier to write. As it's a set of IPs instead of a set of rules it should be faster. Thanks. However I can't seem to find the --match-set option for my Android's iptables version. I Will test.

  Dunno if it's enough, for example: https://whois.arin.net/rest/net/NET-63-150-141-224-1.html https://whois.arin.net/rest/net/NET-63-150-141-224-1.html is Facebook's range not included above.

      Well, good, though that doesn't mean other 50 similar FB IP ranges in other collocation facilities are also not responding to ping.
      • dontchooseanick 6y ago
        https://search.arin.net/rdap/?query=FACEBOOK https://search.arin.net/rdap/?query=FACEBOOK The links contain the IP ranges (4 and 6). Testing all those should be sufficient.
        • megous 6y ago
          What about other continents? Are FB addresses all under ARIN, even in EU? There are some small ranges in RIPE too: https://apps.db.ripe.net/db-web-ui/query?searchtext=facebook https://apps.db.ripe.net/db-web-ui/query?searchtext=facebook
