DomainClassifier

DomainClassifier is a simple Python library to extract and classify Internet domains/hostnames/IP addresses from raw unstructured text files following their existence, localization or attributes.

DomainClassifier can be used to extract Internet hosts from any free texts or collected unstructured information.

Install

DomainClassifier is part of the pypi package. It can be installed using the pip command:

pip install DomainClassifier

In [11]: c = DomainClassifier.domainclassifier.Extract(rawtext="www.google.com foo.bar ppp.ppp")

In [12]: c.potentialdomain()
Out[12]: ['www.google.com', 'foo.bar']

How To Use It

import DomainClassifier.domainclassifier

c = DomainClassifier.domainclassifier.Extract( rawtext = "www.xxx.com this is a text with a domain called test@foo.lu another test abc.lu something a.b.c.d.e end of 1.2.3.4 foo.be www.belnet.be ht
tp://www.cert.be/ www.public.lu www.allo.lu quuxtest www.eurodns.com something-broken-www.google.com www.google.lu trailing test www.facebook.com www.nic.ru www.youporn.com 8.8.8.
8 201.1.1.1")

# extracting potentially valid domains from rawtext
print c.potentialdomain()

# reduce set of potentially valid domains to existing domains
# (based on SOA,A,AAAA,CNAME,MX records)
print c.validdomain(extended=True)

# reduce set of valid domains with DNS records associated to a
# specified country
print "US:"
print c.localizedomain(cc='US')
print "LU:"
print c.localizedomain(cc='LU')
print "BE:"
print c.localizedomain(cc='BE')
print "Ranking:"
print c.rankdomain()

# extract valid IPv4 addresses (using the potential list of valid domains)
print "List of ip addresses:"
print c.ipaddress(extended=True)

# some more filtering
print "Include dot.lu:"
print c.include(expression=r'\.lu$')
print "Exclude dot.lu:"
print c.exclude(expression=r'\.lu$')
