In freenode I know my IP is shown making me vulnerable . Whats the best way to access IRC? Is it tor? I am on Windows 7 but if you have Linux specific solution I am open to them too
The easiest way to hide your IP from other Freenode users is to use a cloak. To get one, register with NickServ and ask for one in the
#freenode channel, as described in the FAQ.
You can ask for an unaffiliated cloak in #freenode. This is our standard cloak and normally shows unaffiliated/youraccountname. You will need a registered nickserv account. Remember to verify your email address. Some of our registered groups offer their own cloaks for their projects. To obtain one of these, you need to find the group contact for the group you are interested in, and ask them to arrange the cloak for you.
Cloaks are not the safest solution though. A safer solution is to use TOR, as described here:
The primary Tor hidden service address for freenode is p4fsi4ockecnea7l.onion. The service listens on ports 6667, 6697 (SSL), 7000 (SSL), and 7070 (SSL). To connect, a NickServ account is needed, and the IRC client must be configured to support SASL
Client-specific instructions for setting up SASL can be found here.
