I looked up my own IP address, and I wanted to play with that whois system from network-tools.com. The strange thing, if I want to get the information, I get the following results (attached). Am I invisible on the web or is there an explination for this?
if your getting interested in networking get yourself a copy of nmap (a port scanner) from Insecure.Org - Nmap Free Security Scanner, Tools & Hacking resources Just remember that some people (large corporations etc) might not take too kindly if they found out you did a port scan of there box (so i would recomend that you only scan things you own, like other computers and your router!)
