Unified hosts file with base extensions
This repository consolidates several reputable
hosts files, and merges them into various unified hosts files
with duplicates removed.
- Here's the raw hosts file containing 26,889 entries.
- Last updated: March 29 2016.
List of all hosts file variants
|Host file recipe||Readme||Raw hosts||Unique domains|
|Unified hosts = (adware + malware)||Readme||link||26,889|
|Unified hosts + gambling||Readme||link||27,604|
|Unified hosts + porn||Readme||link||32,143|
|Unified hosts + social||Readme||link||26,997|

|Unified hosts + porn + social||Readme||link||32,251|
|Unified hosts + gambling + porn + social||Readme||link||32,966|
Expectation: These unified hosts files should serve all devices, regardless of OS.
Sources of hosts data unified here
hosts files from the following locations are always unified and included:
- The Adaway hosts file, updated regularly.
- MVPs.org Hosts file at http://winhelp2002.mvps.org/hosts.htm, updated monthly, or thereabouts.
- Dan Pollock at http://someonewhocares.org/hosts/ updated regularly.
- Malware Domain List at http://www.malwaredomainlist.com/, updated regularly.
- Peter Lowe at http://pgl.yoyo.org/adservers/, updated regularly.
- My own small list in raw form here.
The unified hosts file is extensible. You manage extensions by curating the
extensions/ folder tree.
porn extension which are included in this repo, for example.
Generate your own unified hosts file
updateHostsFile.py script, which is python 2.7 and Python 3-compatible, 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.info text file in each source's folder), otherwise it will use the
hosts file that's already there.
Using Python 3:
python3 updateHostsFile.py [--auto] [--replace] [--ip nnn.nnn.nnn.nnn] [--extensions ext1 ext2 ext3]
Using Python 2.7:
python updateHostsFile.py [--auto] [--replace] [--ip nnn.nnn.nnn.nnn] [--extensions ext1 ext2 ext3]
Command line options:
-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
-eflag to include any you want.
- Your active hosts file is not replaced unless you include the
-r: trigger replacing your active hosts file with the new hosts file. Use along with
--ip nnn.nnn.nnn.nnn, or
-i nnn.nnn.nnn.nnn: the IP address to use as the target. Default is
--extensions <ext1> <ext2> <ext3>, or
-e <ext1> <ext2> <ext3>: the names of subfolders below the
containing additional category-specific hosts files to include in the amalgamation. Example:
--extensions porn or
-e social porn.
-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.
-h: display help.
How do I control which sources are unified?
Add one or more additional sources, each in a subfolder of the
data/ folder, and specify its update url in
Add one or more optional extensions, which originate from subfolders of the
extensions/ folder. Again the url in
update.info controls where this extension finds its updates.
How do I incorporate my own hosts?
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.
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 127.0.0.1 ad.ae.doubleclick.net 127.0.0.1 ad.ar.doubleclick.net 127.0.0.1 ad.at.doubleclick.net 127.0.0.1 ad.au.doubleclick.net 127.0.0.1 ad.be.doubleclick.net # etc...
We recommend using
0.0.0.0 instead of
0.0.0.0 is faster because you don't have to wait for a timeout. It also does not interfere
with a web server that may be running on the local PC.
Why not use just
0 instead of
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
Mac OS X, iOS, Android, Linux:
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.
Mac OS X
Open a Terminal and run:
sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder
Open a Command Prompt:
Windows XP: Start -> Run ->
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"
Open a Terminal and run with root privileges:
sudo /etc/rc.d/init.d/nscd restart
Linux with systemd:
sudo systemctl restart network.service
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

Goals of this unified hosts file
The goals of this repo are to:
automatically combine high-quality lists of hosts,
provide easy 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.
For example, the (huge) hosts file from hosts-file.net is not included here because it is very large (300,000+ entries) and doesn't currently display a corresponding high level of curation activity.
It is expected that this unified hosts file will serve both desktop and mobile devices under a variety of operating systems.
