Is there a way to get all IP addresses of youtube to block it with Windows Firewall?

Question

I want to programme my own anti distraction tool. I can not / do not want to use hosts or third party apps. When using IPSEC or Windows firewall, it only accepts IP adresses. Th

Answer 1

The way to find all the IP addresses associated with a URL is first to find the AS Number, you can get it in http://networktools.nl/asinfo/ For YouTube get it in http://networktools.nl/asinfo/youtube.com There you get the AS Number

Primary ASN : 15169

Now, type in terminal

whois -h whois.radb.net -- '-i origin AS15169' | grep ^route

And there you will get all the IP Addresses, the list is long but you can find similar addresses that can be grouped in a subnet.
