So exist any kind of means to obstruct facebook.com outside the facebook.com domain name?

I require a souliton that is not "webbrowser related" - no Add - on, so as an example : a Privoxy rule.
It would certainly still not work with HTTPS websites, just on HTTP, ok, yet I still require this regulation, yet I do not have an idea what it is. Does any person has?

Thanks!

One time - recognized means of obstructing accessibility to remote websites is by placing "fake" access (generally 127.0.0.1) in the hosts documents.

Basically, modify/ etc/hosts and also add access similar to this :

127.0.0.1    facebook.com
172.0.0.1    apps.facebook.com

FMI on this method, read this ; for even more suggestions of obstructing, read that.

Assuming you have accessibility to your firewall program, You can simply obstruct Facebook is prefixes. You can figure out their ASN from traceroute :

$  traceroute -n -A www.facebook.com
....
14  4.69.149.82 [AS3356]  630.713 ms  633.180 ms 4.69.149.146 [AS3356]  629.633 ms
15  4.53.112.58 [AS3356]  578.959 ms  580.703 ms  579.624 ms
16  204.15.20.120 [AS32934/AS10753]  577.604 ms  557.247 ms  636.807 ms
17  74.119.76.67 [AS32934]  633.454 ms 74.119.76.186 [AS32934]  602.556 ms  603.583 ms
18  74.119.76.197 [AS32934]  634.461 ms 74.119.76.205 [AS32934]  634.431 ms 74.119.77.55 [AS32934]  702.079 ms
19  69.63.190.10 [AS32934/AS10753]  701.423 ms  700.644 ms  700.937 ms

Which you can validate with devices such as these

$ dig +short AS32934.asn.cymru.com TXT
"32934 | US | arin | 2004-08-24 | FACEBOOK - Facebook, Inc."

Then you would certainly get their prefixes making use of a lookup service

$ lynx --dump https://www.dan.me.uk/bgplookup?asn=32934 2>&1 | grep AS32934
   IPv4 Prefixes seen at AS32934:
     204.15.20.0/22       [AS32934]
     2620:0:1c00::/40     [AS32934]
     66.220.144.0/21      [AS32934]
     66.220.152.0/21      [AS32934]
     66.220.159.0/24      [AS32934]
     69.171.224.0/20      [AS32934]
     69.171.239.0/24      [AS32934]
     69.171.240.0/20      [AS32934]
     69.171.255.0/24      [AS32934]
     69.63.176.0/21       [AS32934]
     69.63.184.0/21       [AS32934]
     74.119.76.0/22       [AS32934]

You can after that feed the prefixes right into your firewall program.

Certainly, If I am an established customer, I can make use of any one of the free proxies around providing this entire blog post moot.
