Does Windows 10 Mobile use a Hosts file? I ask because without an ad blocker, mobile browsers are a nightmare, so I would like to use a modified hosts file to restore some sanity. I just had a script run on a website opened from a link in the MSN Sports app that required a freaking reset of the phone to clear. I understand that ads enable content, but the ads themselves have become so dangerous, I cannot allow them. Until the advertisers cease automatically playing videos and sound, running scripts, and otherwise acting like digital a.holes, I have no compunction about banishing them.
This article shows you how to use a free PowerShell script to block bad domain names by modifying the on Windows computers. You can run the script manually, as a scheduled job, or push it out through Group Policy for enterprise-wide deployment.
This is a script we use in the Securing Windows and PowerShell Automation course at SANS conferences. Download the to get the Update-HostsFile.ps1 script (look under Day6-Servers DNS): Note: Why is this script any different than other HOSTS file tools out there? The script puts nine names on each line of the file, which optimizes lookup performance greatly. The script can take multiple local, SMB or HTTP paths to multiple input files to create one new HOSTS file with redundant names removed.
It can create duplicate names with 'www.' Prepended if necessary. And because it's a public domain PowerShell script instead of a licensed binary, it's easy to customize without any legal worries. Background A trick to block the domain names used by malware, spyware and advertising sites is to add these names to one's HOSTS file using an invalid IP address such as '0.0.0.0'. When the malware on an infected computer, for example, attempts to resolve a fully-qualified domain name (FQDN), perhaps to download the next stage malicious binary, if this FQDN is in the HOSTS file, the malware should fail to resolve the correct IP address. To blackhole unwanted domain names like this, you can modify a computer's HOSTS file or modify the DNS server used by that computer.
Note: Here is a PowerShell script to manage too.
On occasion you will need to edit the hosts file on your machine. Sometimes because of an attack or prank, and others so that you can simply and freely control access to websites and network traffic. Hosts files have been in use since ARPANET. They were used to resolve hosts names before DNS. Hosts files would be massive documents used to aide the network name resolution.
Microsoft kept the hosts file alive in Windows networking which is why it varies very little whether used in Windows, macOS, or Linux. The syntax stays mostly the same across all platforms. Most hosts files will have several entries for loopback.
We can use that for the basic example for the typical syntax. The first part will be the location to redirect the address to, the second part will be the address that you will want to redirect, and the third part is the comment.
They can be separated by a space, but for ease of reading are typically separated by one or two tabs. 127.0.0.1 localhosts #loopback Now let’s look at accessing the hosts files in the different operating systems.
Windows 8 or 8.1 or 10 Unfortunately Windows 8 or 10 makes it annoying to open apps as administrator — but it’s not too difficult. Just search for Notepad, then right-click on Notepad in the search results list, and choose to run it as administrator. If you’re using Windows 10 this will be on the Start Menu.
If you’re using Windows 10, it’ll look more like this: Once you’ve done so, open up the following file using the File - Open feature. C: windows system32 drivers etc hosts Then you can edit as normal. Windows 7 To access the hosts file in Windows 7 you can use the following command in the Run Line to open notepad and the file. Notepad c: windows system32 drivers etc hosts Once notepad is open you can edit the file. In this example we will block Facebook. To do this just enter in the following after the # mark.
0.0.0.0 Now that you have edited your Hosts file make sure to save it. Now notice if we try to access Facebook in IE we can’t get to the page. We also were not able to get to it in Google Chrome (check notes at the end). Also for more info on editing your Hosts file, check out The Geek’s article on.
Ubuntu In Ubuntu 10.04 and most Linux distro’s you can edit the hosts file directly in the terminal. You can use your favorite editor or even open your favorite GUI text editor. For this example we will use VIM.
Like Windows 7, Ubuntu’s hosts file is located in the /etc/ folder, though here it is in the root of the drive. In order to edit the file you will need to open it as root which is why we use sudo here. Now that it is open we can edit it to redirect Facebook into nothing. You will notice that with Ubuntu there is also a section for IP6. For most needs you will only need to edit it the top section and ignore the IP6. Now we can save the file and try to go to Facebook.com. Just like in windows we will see that we are now redirected to a site that does not exist.

MacOS (Any Version) In macOS, accessing the hosts file is very similar to Ubuntu. Begin in terminal and use your favorite editor, even is you wish to call a GUI text editor, it is easier to do so from terminal. The file will look a bit more like Windows, only with a little less explanation.
Again we are going to redirect Facebook. This time it seems that 0.0.0.0 is a loopback and will direct you to the computers Apache test page. Notes There are some things to note from this walkthrough that we did notice. When tested it, Chrome did not use the hosts file in any operating system but we were able to block Facebook in Chrome by adding www.facebook.com.
Also, make sure to place and extra line after the last entry for the section. This should get you started in understanding the Hosts file and how it can help protect your computer.
You can use it to block sites that you don’t want a PC to be able to access. If you have more suggestions for any of the operating systems we coved, then leave a comment and let us know!
Hosts Blocker works by updating the Windows default with external information on potential online threats. While the benefits of having an active Internet connection can hardly be overstated, browsing online resources can sometimes have significant negative repercussions on users. From nagging pop-ups to adware and even malware, all these elements can disrupt one's online experience and even damage the system configuration. To avoid such situations, Hosts Block offers a simple and practical protective solution. When browsing online, these domain entries are automatically blocked by Windows, thus allowing one an ad-free Internet experience. Hosts Blocker Features:. Active Protection: Malware wont be able to change the hosts file.

There are so many sites out there you do not want either your employees or your family to see. There are also equally as many ways to stop those sites from being viewed - from a simple third-party software solution to one involving a hardware proxy. But did you know, there is a very simple solution built right into, which allows you to block unwanted sites from being viewed on a PC? That solution is the hosts file. Simply stated, the Windows hosts file is used to map IP addresses to Human Readable Names. This service is normally handled with a domain name server (DNS), but the hosts file allows you to bypass that server (When, say DNS isn't available). But more importantly, the hosts file is in direct control of what the computer can and cannot see.
To this end, a PC can be configured such that it can or cannot see a specific address. That is what I want to address - the blocking of unwanted addresses in the Windows hosts file. This blog post is also available in the PDF format in a. The examples and images used in this blog post regard Windows 7.
The hosts file in earlier versions of Windows can be used in a similar fashion, but the configuration may not be exactly the same. Locating and editing the hosts file The Windows hosts file is located ( Figure A) in C: Windows System32 drivers etc. In order to edit and save the hosts file, administrative rights must be used. Even if a user is logged into an account without administrative privileges, this can be overcome, by following these steps: 1. Click on Start All Programs Accessories. Right-click the hosts file from within Windows Explorer 2.
Select Properties 3. Uncheck Read-only ( Figure B) 4.
Click Yes in the UAC (if prompted) 5. Click OK in the Properties window to complete the process Figure B Uncheck read only if it is checked Format of the hosts file The format of the entries in the hosts file looks like this ( Figure C): IPADDRESS domain name Figure C Format of the entries in the hosts file That is the basic mapping from IP to domain. Each line represents a single mapping. For example, an internal IP address to a hostname would be made with an entry like this: 192.168.100.21 bodhi-linux Once the file is saved, the machine at the address 192.168.100.21 can be reached using the name bodhi-linux. Blocking Adware and/or unwanted sites This is where the 'trick' comes in. There is an address, called the loopback address, on a computer that refers to itself. If the loopback address is pinged, the machine being pinged would be the machine doing the pinging.
The IP address of the loopback is always 127.0.0.1 (that is the case in Windows, Linux, and Mac.). Using that loopback address, any unwanted domain name can be re-directed back to the local machine. A hosts file entry for this would look like: 127.0.0.1 unwanted.domain Where unwanted.domain is the domain to be blocked. So what needs to be done with the hosts file is: 1. Open the hosts file with administrative privileges 2. Add all of the entries you need to block all of the sites you want to block 3. Save the hosts file 4.

Reset the hosts file to read-only There is another issue that can rear its ugly head. When saving the hosts file in Notepad, Notepad is going to want to append the.txt extension to the file. Make sure this doesn't happen by either selecting All Files from the Save as type drop-down, or renaming the file from hosts.txt to hosts from within Explorer. Another trick Say there are sites employees are forbidden to visit (Facebook, ebay, etc). To make sure the employees are always aware of the policy, you can set up a Web server that all unwanted URLs can be directed to. On that Web server you would have the company policy regarding unwanted Web surfing available.
To set this up in the hosts file add a line similar to the one below (assuming the web server is at address 192.168.100.21): 192.168.100.21 unwanted.domain Where unwanted.domain is the actual domain to be re-directed. Now, when a user goes to unwanted.domain that user will be automatically directed to 192.168.100.21, which will display the policy. Pre-set hosts file For those that do not want to go through and add a ton of unwanted adware sites and other malicious sites to the hosts file on every PC in an organization, this file can be downloaded, unzipped, and put in place of the current hosts file on each PC.

Once that file is unzipped, make sure to look it over and make any necessary additions, before putting it into place. Final thoughts There are so many ways to block unwanted sites, but it's nice to know the task can be done without having to rely on third-party software. Window's use of the hosts file makes for a very flexible tool to fine-tune what sites a computer can and cannot access. Related Topics.
