    Hi all,

    I'm on a mission to find, spider, mine and publish all domainnames of the .nl extension. So far I have managed quite easy to find over 200 k of sites, but there are about 4 million. I have noticed by doing a reverse dns by hand that some domains are on shared servers with hundreds of other domains that my spider wouldt other wise find. Do any of you know if there is a mass reverse DNS tool that spiders a list of urls and performs reverse DNS lookups on a domain to look which other domains are on that server?
    Anyone have a cunning idea on how I can find 4 million .nl website adresses?

    Regards

    Rob
