Detect the registered domains for given hostnames based on Mozillas effective TLD listing

Project description

pyregdom - Python library for Mozilla Public Suffix list

A Python version of usrflo’s regdom libs to detect the registered domain for a given domain name, based on Mozillas effective TLD listing.

Installation

From source code:

$ sudo python setup.py install

Using pip:

$ pip install pyregdom

Usage

>>> import regdom

>>> regdom.get_registered_domain("mail.google.com")
'google.com'

>>> regdom.get_registered_domain("foobar.github.io")
'foobar.github.io'

>>> regdom.get_registered_domain("a.b.c.city.kawasaki.jp")
'city.kawasaki.jp'

>>> regdom.get_registered_domain("invalid_domain_name.com") # return None

>>> regdom.get_registered_domain("not-recognized-tld.smile")
'not-recognized-tld.smile'

>>> regdom.get_registered_domain("not-recognized-tld.smile", fallback=False) # return None

Update the list

Simply run the script generate_effective_tlds.py under scripts directory, it will download and parse the latest Mozilla Public Suffix

$ scripts/generate_effective_tlds.py

Then re-install the module from source.

You can also use your own list file:

$ scripts/generate_effective_tlds.py your_own_list_file.dat

The script doesn’t check for the format of the file so make sure you have it in the same format defined at Mozilla Public List.

Author of this module will also update pyregdom on pypi every month if there are changes in the list.

Source code

Source code is hosted at Github, you can get a local copy of the development repository with:

$ git clone https://github.com/huyphan/pyregdom
