The Ultimate Hosts Blacklist (UHB) is undoubtedly one of the world's largest curated and unified hosts file to protect your network, computer, device, children, or family against over several hundred thousand malicious actors.
All our information is gathered from multiple sources, tested regularly and merged into one massive file which is updated daily. Our hosts can be used on almost all operating system but we also propose 2 DNS servers that ingest and block the bad actor as good - if not better - than a hosts file.

If all our files are too large for your device to ingest or if you don't want
to think about updating the hosts file every night, you can use
our DNS servers.
They are not logging anything and are available round the clock.
From time to time we may need to process some maintenance that requires a downtime of less than 120 seconds.
We will never put downtime on both servers at the same time. But, if you want to get informed about when downtime is scheduled, please follow/subscribe to the Maintenance Thread.
NOTICE: THIS IS THE RECOMMENDED METHOD FOR WINDOWS USER.

A hosts file, named hosts (with no file extension), is a plain-text file used
by all operating systems to map a hostname 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,
ransomware, porn and other nuisance domains.
A hosts file like this causes any lookups to any of the listed domains to
resolve back to your localhost so it prevents any outgoing connections to the
listed domains.
For example, to drop all requests to certain domains or servers, adding lines
to your hosts file as below will achieve this for you.
You can create your custom hosts or simply use ours which covers you for
well over 539,849 bad domains.
# Block Bad Domains and Servers with Hosts File
0.0.0.0 doubleclick.net
0.0.0.0 18chinese.com
0.0.0.0 gatekeeper.tss.net
0.0.0.0 www.gatekeeper.tss.net
0.0.0.0 cdn.gatekeeper.tss.net
0.0.0.0 youporn.com
0.0.0.0 www.youporn.com
0.0.0.0 x-lime.net
0.0.0.0 www.x-lime.net
# etc ... etc .... etc ...
It is important to note that a hosts file cannot understand wild card domains.
So adding 0.0.0.0 *.doubleclick.net will not work. You must specify every
variation of a domain name that is in use and up to no good.
Lucky for you our massive hosts file compiled from over
several input sources already does this for you. So it is as simple as
downloading our hosts file and keeping it up to date as we update the hosts
file several times a week as new threats emerge.
Most host files traditionally use 127.0.0.1 as the loopback address,
to establish an IP connection to the local machine.
I prefer the use of 0.0.0.0, which is defined as a non-routable meta-address.
Using 0.0.0.0 is also faster because there's no wait for a timeout resolution.
It also does not interfere with any web servers that may be running on the
local system.
For many Windows versions however, 127.0.0.1 does appear to work slightly
better and which is why our Windows version of the hosts file uses
127.0.0.1 as the loopback address.
A hosts file, named hosts.deny is a plain-text file for Linux/Unix based
operating systems only which blocks a list of IP addresses on the outside of
your network from gaining any access to your computer.
A hosts.deny file will not work on a Windows operating system.
The superhosts.deny file is simply named superhosts.deny but is just a
normal hosts.deny file which is a plain-text file for Linux/Unix based
operating systems that blocks a list of IP addresses or hosts (domains) on the
outside of your network from gaining any access to your computer.
If you want to use this superhosts.deny file simply rename it to
hosts.deny and place it in your /etc/ folder on your Linux/Unix
operating system.
A hosts.deny file will not work on a Windows operating system.
To modify your current hosts file, look for it in the following places
and modify it with a text editor.
PLEASE NOTE: On all operating systems you need administrative access to
modify the hosts file.
Linux, Mac OS X, iOS, Android: /etc/hosts
Linux, Mac OS X, iOS, Android: /etc/hosts.deny
Windows Systems (NOT RECOMMENDED: PREFER DNS SERVER): %SystemRoot%\system32\drivers\etc\hosts Try the Windows Installer Batch Script
Our hosts file is generated from multiple input sources, collated, sorted for
duplicates and merged into one single hosts file.
