Unified hosts file with fakenews, social extensions
This repository consolidates several reputable hosts
files, and merges them
into a unified hosts file with duplicates removed. A variety of tailored hosts files are provided.
- Last updated: April 09 2020.
- Here's the raw hosts file with fakenews, social extensions containing 58,366 entries.
- Logo by @Tobaloidee.
List of all hosts file variants
This repository offers 15 different host file variants, in addition to the base variant.
The Non GitHub mirror is the link to use for some hosts file managers like Hostsman for Windows that don't work with GitHub download links.

Extensions
The unified hosts file is optionally extensible. Extensions are used to include domains by category. Currently, we offer the following categories: fakenews
, social
, gambling
, and porn
.
Extensions are optional, and can be combined in various ways with the base hosts file. The combined products are stored in the alternates
folder.
Data for extensions are stored in the extensions
folder. You manage extensions by curating this
folder tree, where you will find the data for fakenews
, social
, gambling
, and porn
extension data that we maintain and provide for you.
Generate your own unified hosts file
To generate your own unified hosts file you will need Python 3.5 or later.
First, install the dependencies with:
pip3 install --user -r requirements.txt
Note we recommend the --user
flag which installs the required dependencies at the user level. More information about it can be found on pip documentation.
To run unit tests, in the top-level directory, run:
python3 testUpdateHostsFile.py
The updateHostsFile.py
script will generate a unified hosts file based on the sources in the
local data/
subfolder. The script will prompt you whether it should fetch updated versions
(from locations defined by the update.json
text file in each source's folder). Otherwise, it
will use the hosts
file that's already there.
Usage
Using Python 3:
python3 updateHostsFile.py [--auto] [--replace] [--ip nnn.nnn.nnn.nnn] [--extensions ext1 ext2 ext3]
Command line options:
--help
, or -h
: display help.
--auto
, or -a
: run the script without prompting. When --auto
is invoked,
- Hosts data sources, including extensions, are updated.
- No extensions are included by default. Use the
--extensions
or-e
flag to include any you want. - Your active hosts file is not replaced unless you include the
--replace
flag.
--backup
, or -b
: Make a backup of existing hosts file(s) as you generate
over them.
--extensions <ext1> <ext2> <ext3>
, or -e <ext1> <ext2> <ext3>
: the names
of subfolders below the extensions
folder containing additional
category-specific hosts files to include in the amalgamation. Example:
--extensions porn
or -e social porn
.
--flush-dns-cache
, or -f
: skip the prompt for flushing the DNS cache.
Only active when --replace
is also active.
--ip nnn.nnn.nnn.nnn
, or -i nnn.nnn.nnn.nnn
: the IP address to use as the
target. Default is 0.0.0.0
.
--keepdomaincomments
, or -k
: true
(default) or false
, keep the comments
that appear on the same line as domains. The default is true
.
--noupdate
, or -n
: skip fetching updates from hosts data sources.
--output <subfolder>
, or -o <subfolder>
: place the generated source file
in a subfolder. If the subfolder does not exist, it will be created.
--replace
, or -r
: trigger replacing your active hosts
--skipstatichosts
, or -s
: false
(default) or true
, omit the standard
section at the top, containing lines like 127.0.0.1 localhost
. This is
useful for configuring proximate DNS services on the local network.
--nogendata
, or -g
: false
(default) or true
, skip the generation of the
readmeData.json file used for generating readme.md files. This is useful if you are
generating host files with additional whitelists or blacklists and want to keep your
local checkout of this repo unmodified.
--compress
, or -c
: false
(default) or true
, Compress the hosts file
ignoring non-necessary lines (empty lines and comments) and putting multiple
domains in each line. Reducing the number of lines of the hosts file improves
the performances under Windows (with DNS Client service enabled).
--minimise
, or -m
: false
(default) or true
, like --compress
, but puts
each domain on a separate line. This is necessary because many implementations
of URL blockers that rely on hosts
files do not conform to the standard which
allows multiple hosts on a single line.
How do I control which sources are unified?
Add one or more additional sources, each in a subfolder of the data/
folder, and specify the url
key in its update.json
file.
Add one or more optional extensions, which originate from subfolders of the
extensions/
folder. Again the url in update.json
controls where this
extension finds its updates.
Create an optional blacklist
file. The contents of this file (containing a
listing of additional domains in hosts
file format) are appended to the
unified hosts file during the update process. A sample blacklist
is
included, and may be modified as you need.
- NOTE: The
blacklist
is not tracked by git, so any changes you make won't be overridden when yougit pull
this repo fromorigin
in the future.
How do I include my own custom domain mappings?
If you have custom hosts records, place them in file myhosts
. The contents
of this file are prepended to the unified hosts file during the update
process.
The myhosts
file is not tracked by git, so any changes you make won't be
overridden when you git pull
this repo from origin
in the future.
How do I prevent domains from being included?
The domains you list in the whitelist
file are excluded from the final hosts
file.
The whitelist
uses partial matching. Therefore if you whitelist
google-analytics.com
, that domain and all its subdomains won't be merged
into the final hosts file.
The whitelist
is not tracked by git, so any changes you make won't be
overridden when you git pull
this repo from origin
in the future.
How can I contribute hosts records?
If you discover sketchy domains you feel should be included here, here are some ways to contribute them.
Option 1: contact one of our hosts sources
The best way to get new domains included is to submit an issue to any of the data providers whose home pages are listed here. This is best because once you submit new domains, they will be curated and updated by the dedicated folks who maintain these sources.
Option 2: add your domains to Steven Black's personal data file
Fork this hosts this repo and add your links to https://github.com/StevenBlack/hosts/blob/master/data/StevenBlack/hosts.
Then, submit a pull request.
WARNING: this is less desirable than Option 1 because the ongoing curation falls on us. So this creates more work for us.
Option 3: create your own hosts list as a repo on GitHub
If you're able to curate your own collection of sketchy domains, then curate your own hosts list. Then signal the existence of your repo as a new issue and we may include your new repo into the collection of sources we pull whenever we create new versions.
What is a hosts file?
A hosts file, named hosts
(with no file extension), is a plain-text file
used by all operating systems to map hostnames to IP addresses.
In most operating systems, the hosts
file is preferential to DNS
.
Therefore if a domain name is resolved by the hosts
file, the request never
leaves your computer.
Having a smart hosts
file goes a long way towards blocking malware, adware,
and other irritants.
For example, to nullify requests to some doubleclick.net servers, adding these lines to your hosts file will do it:
# block doubleClick's servers
0.0.0.0 ad.ae.doubleclick.net
0.0.0.0 ad.ar.doubleclick.net
0.0.0.0 ad.at.doubleclick.net
0.0.0.0 ad.au.doubleclick.net
0.0.0.0 ad.be.doubleclick.net
# etc...
We recommend using 0.0.0.0
instead of 127.0.0.1
Traditionally most host files use 127.0.0.1
, the loopback address, to establish an IP connection to the local machine.
We prefer to use 0.0.0.0
, which is defined as a non-routable meta-address used to designate an invalid, unknown, or non-applicable target.
Using 0.0.0.0
is empirically faster, possibly because there's no wait for a timeout resolution. It also does not
interfere with a web server that may be running on the local PC.
Why not use 0
instead of 0.0.0.0
?
We tried that. Using 0
doesn't work universally.
Location of your hosts file
To modify your current hosts
file, look for it in the following places and modify it with a text
editor.
macOS (until 10.14.x macOS Mojave), iOS, Android, Linux: /etc/hosts
file.
macOS Catalina: /private/etc/hosts
file.
Windows: %SystemRoot%\system32\drivers\etc\hosts
file.
Gentoo
Gentoo users may find sb-hosts
in ::pf4public Gentoo overlay
Updating hosts file on Windows
(NOTE: See also some third-party Hosts managers, listed below.)
On Linux and macOS, run the Python script. On Windows more work is required due to compatibility issues so it's preferable to run the batch file as follows:
updateHostsWindows.bat
This file MUST be run in command prompt with administrator privileges in the repository directory. In addition to updating the hosts file, it can also replace the existing hosts file, and reload the DNS cache. It goes without saying that for this to work, you must be connected to the internet.
To open a command prompt as administrator in the repository's directory, do the following:
Windows XP: Start → Run → cmd
Windows Vista, 7: Start Button → type cmd
→ right-click Command Prompt →
"Run as Administrator"
Windows 8: Start → Swipe Up → All Apps → Windows System → right-click Command Prompt → "Run as Administrator"
Windows 10: Start Button → type cmd
→ right-click Command Prompt →
"Run as Administrator"
You can also refer to the "Third-Party Hosts Managers" section for further recommended solutions from third parties.
Reloading hosts file
Your operating system will cache DNS lookups. You can either reboot or run the following commands to manually flush your DNS cache once the new hosts file is in place.
The Google Chrome browser may require manually cleaning up its DNS Cache on chrome://net-internals/#dns page to thereafter see the changes in your hosts file. See: https://superuser.com/questions/723703 |
---|
Windows
Open a command prompt with administrator privileges and run this command:
ipconfig /flushdns
Before flushing the DNS cache, open a command prompt with administrator privileges and run this command:
sc config "Dnscache" start=disabled
sc stop "Dnscache"
Linux
Open a Terminal and run with root privileges:
Debian/Ubuntu sudo service network-manager restart
Linux Mint sudo /etc/init.d/dns-clean start
Linux with systemd: sudo systemctl restart network.service
Fedora Linux: sudo systemctl restart NetworkManager.service
Arch Linux/Manjaro with Network Manager: sudo systemctl restart NetworkManager.service
Arch Linux/Manjaro with Wicd: sudo systemctl restart wicd.service
RHEL/Centos: sudo /etc/init.d/network restart
FreeBSD: sudo service nscd restart
To enable the nscd
daemon initially, it is recommended that you run the following commands:
sudo sysrc nscd_enable="YES"
sudo service nscd start
Then modify the hosts
line in your /etc/nsswitch.conf
file to the following:
hosts: cache files dns
Others: Consult this Wikipedia article.
macOS
Open a Terminal and run:
sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder
Release management
This repository uses release-it, an excellent CLI release tool for GitHub repos and npm packages, to automate creating releases. This is why the package.json and .release-it.json files are bundled.
Goals of this unified hosts file
The goals of this repo are to:
-
automatically combine high-quality lists of hosts,
-
provide situation-appropriate extensions,
-
de-dupe the resultant combined list,
-
and keep the resultant file reasonably sized.
A high-quality source is defined here as one that is actively curated. A hosts source should be frequently updated by its maintainers with both additions and removals. The larger the hosts file, the higher the level of curation is expected.
It is expected that this unified hosts file will serve both desktop and mobile devices under a variety of operating systems.

Interesting Applications
-
Hostile is a nifty command line utility to easily add or remove domains from your hosts file. If our hosts files are too aggressive for you, you can use
hostile
to remove domains, or you can usehostile
in a bash script to automate a post process each time you download fresh versions of hosts. -
macOS Scripting for Configuration, Backup and Restore helps customizing, re-installing and using macOS. It also provides a script to install and update the hosts file using this project on macOS. In combination with a launchd it updates the hosts file every x days (default is 4). To install both download the GitHub repo and run the install script from the directory one level up.

dnsmasq conversion script This GitHub gist has a short shell script (bash, will work on any 'nix) and uses
wget
&awk
present in most distros, to fetch a specified hosts file and convert it the format required by dnsmasq. Supports IPv4 and IPv6. Designed to be used as either a shell script, or can be dropped into /etc/cron.weekly (or wherever suits). The script is short and easily edited, also has a short document attached with notes on dnsmasq setup.
