I decided to start a Internet Censorship 101 series of articles that takes a look at and explains the various methods of censorship on the internet and possible solutions to this situation for the user who tries to access information that are blocked / censored. I’m going to start with a relatively weak form of censorship called DNS Filtering.

I have written a small php script that lookups your IP, your browser, the refering site and the remote port. The website has no ads at all and loads pretty fast. This might be useful for those who are using proxys and want to check if those proxys are spilling their IP address or not. The RIAA for example is identifying downloaders by their IP address.

Angry Ip Scanner is a small open source application that lets you scan IP addresses and ports, you can even specifiy the range of the scan by yourself. After pinging the target IP it is able to resolve other data like hostname, MAC address and open ports.

CurrPorts displays the list of all currently opened TCP/IP and UDP ports on your local computer. For each port in the list, information about the process that opened the port is also displayed, including the process name, full path of the process, version information of the process (product name, file description, and so on), the time that the process was created, and the user that created it.

Everything you do on the net transmitts your Ip Address. If you chat with someone he could easily find it out, if you write an email the information will be transmitted with the email.

The article describes what the IP reveals about the user behind.
