What are some online brazilian forums?

In online forums, what is the Whois feature?

• Many of the software used to create forums have a Whois feature. What does this do? What does it mean when someone is performing a "Whois" or a "Whois search"?

• Answer:

  Everytime you make connection with the internet, you obtain an IP-address. This allows you to use the network and to identify you as unique. To prevent illegal activity the use of IP-addresses is restricted and registered. The Whois, allows us to locate the IP-address. Like: IP 123.134.12.3 is from Nigeria (just a fictional example). Whois is a handy tool to contact the hosting provider in case of problems. Like 'Whois identifies 123.134.12.3 as a Russion user hosted by Great Hosting Provider'. In case of problems you can contact (in this example) Great Hosting Provider with the details or the police force with all the details you have found by using Whois. Only the justice department/police can access the personal information like the name and billing address and such.
