How to block all servers of a service? For example, you want to block all of roblox, as roblox has a different server for its website and for its various games, etc. When I run ping www.roblox.com, I get:

ping www.roblox.com
Pinging www.roblox.com [] with 32 bytes of data:
Reply from bytes=32 time=66ms TTL=246
Reply from bytes=32 time=68ms TTL=246
Reply from bytes=32 time=68ms TTL=246
Reply from bytes=32 time=66ms TTL=246
Ping statistics for
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 66ms, Maximum = 68ms, Average = 67ms

I get the IP address and, but which one should I block? Which is the server and which is the web server?


When I run nslookup www.roblox.com, it gives me:

nslookup www.roblox.com
Server:  UnKnown

Non-authoritative answer:
Name:    www.roblox.com

    Instead of ping, run nslookup to get a list of the IPs. – mt025 Feb 4 '18 at 4:29

    Where are you getting from? – DavidPostill Feb 4 '18 at 9:44
  • @DavidPostill I get it from ping roblox.com – ds_secret Feb 4 '18 at 16:23
  • But its never shown in any of your output? Depending on their DNS configuration you won't be able to just ask them for a list of all their IPs. It's also unclear whenever you're trying to block incoming or outgoing traffic. Depending on the tools that are available and what/how you're trying to block you might be able to just use the DNS name. – Seth Feb 6 '18 at 11:10
  • @Seth I did explain it in my question. It is in the first {} part. – ds_secret Feb 7 '18 at 0:52

Open notepad as Administrator:

  1. Open Start

  2. Type notepad

  3. Right click and press Run as Administrator

Press File > Open, then navigate to C:\Windows\System32\drivers\etc. Click the dropdown so that it shows all file types, then double-click the 'hosts' file (it has no file extension).

Go to the bottom, then type: www.roblox.com

Save the document, then close. Access to the domain www.roblox.com will be routed to the IP address, which doesn't exist. Incidentally, this is the method used by Spybot Anti-Beacon, the anti-Windows-10-surveillance tool.

  • I found this on another site and they told me to use the IP. – ds_secret Feb 4 '18 at 16:44
  • Also does it block only the web server at roblox.com or both the web server and the game server. – ds_secret Feb 4 '18 at 16:45
  • @ds_secret this will block any traffic on any protocol, so both of the above. You can route it to or as sends you nowhere and routes to your local machine - technically, this is less robust. You can do either, but for "reasons" I recommend – Tom Harris Feb 4 '18 at 21:17

    It's the easiest approach but does have a caveat. If you do have other related domain names like robolox.com (missing the www.) or gameserver.robolox.com those won't be blocked unless you list each DNS name individually. – Seth Feb 7 '18 at 6:45

    As far as I can tell you can't use wildcards and yes, for that single DNS name it works. Even if you add more but depending on what she/he knows about how their services operate (multiple game servers) it might be necessary to add more DNS names. So I just wanted to point it out. – Seth Feb 7 '18 at 8:03
