ARIN Whois Scraper

Description:

This is a little scraper that queries the ARIN database for information on a particular IP address.

Platform:

  • no platform specific code, should work anywhere that has Python
  • Language:

  • Python
  • License:

  • This was based on some generic "found on the internet" whois code, so I'm not sure who to attribute here. The script is just provided as a teaching example.
  • Code:

    import os, sys, string, time, getopt, socket, select, re
    
    NoSuchDomain = "NoSuchDomain"
    
    def whois(domainname, whoisserver=None, cache=0):
      if whoisserver is None:
        whoisserver = "whois.networksolutions.com"
    
      if cache:
        fn = "%s.dom" % domainname
        if os.path.exists(fn):
          return open(fn).read()
    
      page = _whois(domainname, whoisserver)
    
      if cache:
        open(fn, "w").write(page)
    
      return page
    
    def _whois(domainname, whoisserver):
      s = None
    
      ## try until we are connected
      while s == None:
        try:
          s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
          s.setblocking(0)
          try:
            s.connect((whoisserver, 43))
          except socket.error, (ecode, reason):
            if ecode in (115, 150): pass
            else:
              raise socket.error, (ecode, reason)
          ret = select.select([s], [s], [], 30)
    
          if len(ret[1])== 0 and len(ret[0]) == 0:
            s.close()
            raise TimedOut, "on connect "
          s.setblocking(1)
    
        except socket.error, (ecode, reason):
          print ecode, reason
          time.sleep(10)
          s = None
    
    
      s.send("%s \n\n" % domainname)
      page = ""
      while 1:
        data = s.recv(8196)
        if not data: break
        page = page + data
    
      s.close()
    
      print page
    
    
    
    whois("64.233.161.99", "whois.arin.net")
