Some networks have a usermode +x, which will mask your IP address. It requires you to have a registered account, on most networks. Once you've identified, you can do:
Some networks have the option to enable vhosts or cloaks. Enabling vhost will turn
Linkas@22.214.171.124 to Linkas@some.vhost.here

Some networks like freenode provide users with cloaks. It's used to show affiliation (or lack thereof) to a particular group or project, but it also masks your IP as a side-effect. To get a cloak, you can join the #help channel for that network, and request a cloak there.
Some networks allow access via Tor. The instructions for setting up Tor on freenode network can be found in the links given below:
