DomainClassifier
================

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

DomainClassifier can be used to extract Internet hosts from any free texts.

![An overview of the DomainClassifier methods](https://raw.github.com/adulau/DomainClassifier/master/doc/domainclassifier-flow.png)

How To Use It
-------------

```python
import domainclassifier

c = 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.domain()

# 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$')
print "Exclude dot.lu:"
print c.exclude(expression=r'\.lu$')
```
