What are the top 5 most expensive domain names?

What is the best method to script the detection of domain and HTML info for a list of domain names.

• My client is a domain broker and gets given a list of several thousands domain names by possible sales opportunities and my client wants me to write a reusable tool to read in the URLs and detect for each the following attributes: Domain registration status Domain registration date Dns records (A, MX) IP address of host Whois record (to insure ownership) Nslookup of IP or IP Whois Whois data Google page rank Google links to the URL Alexa rank HTML Meta tags Date of HTML last updated Search HTML for an array of keywords and tag where relevant (eg wordpress or <table>) What method or languages would you use to easily identify most of these for the least amount of effort. I had been thinking of Loading records into SQL and then stepping a python or php script to step through these ideally to a series of appropriate APIs. Or even a VB or autohotkey webscraper script? Horrid but could get it done.

• Answer:

  A webscraping script would be a quick and dirty way, but bombarding a lookup service with a huge number of requests might look suspicious.
