Hi, For the ones interested. It's possible to check domain names on an IP address at networktools.nl. This could be used to map virtual hosts on a server. For an example see networktools.nl/?toolAction=toolReverseIP&toolInput=157.166.224.25 . There no limit on the amount of lookups nor is there a captcha limitation against automated lookups.
Thanks, it is a great service. So much so that I put a post on my SEO/SEM/Webmaster blog here - New FREE Webmaster Tools Thanks again...
