updateHostsFile.py can handle either simply combining local hosts files you have checked in, or it can go out to the Internet to update your source files. It also handles automatically generating a header and removing duplicates from the list.

#Amalgamated hosts file
This repo consolidates several reputable hosts files and consolidates them into a single hosts file that you can use.
Currently this hosts file contains 24245 unique entries.
Source of host data amalgamated here
Currently the hosts files from the following locations are amalgamated:
- MVPs.org Hosts file at http://winhelp2002.mvps.org/hosts.htm, updated monthly, or thereabouts.
- Dan Pollock at http://someonewhocares.org/hosts/ updated regularly.
- My own small list in raw form here.
You can add any additional sources you'd like under the data/ directory. Provide a copy of the current hosts file and a file called
update.info with the URL to the hosts file source. This will allow updateHostsFile.py to automatically update your source.
Using updateHostsFile.py
This Python script will generate a unique hosts file based on the sources provided. You can either have the script go out and fetch
an updated version over the web (defined by the update.info text file in the source's directory), or it will use the hosts file you
already have checked into your source's data folder.
Usage
python updateHostsFile.py
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 host 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...
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.
Mac OS X, iOS, Android: /etc/hosts folder.
Windows: %SystemRoot%\system32\drivers\etc\hosts folder.
