I registered a "foo" account on freenode irc server. When I run 

/whowas foo

I can see the last login of "foo" user and public IP. I want to remove that information and I have tried to connect/disconnect many times but all logins are tracked.

  1. How many of such logins are tracked? (better: how many login/logout I must do to remove some entry?)

  2. Is there a way to remove login history?

On all IRC servers I've seen, the WHOWAS information is stored in memory. It will be removed automatically after a short amount of time (on the order of hours, typically). The information is updated every time you log out, so logging in and logging out will extend its lifespan.

Some IRC services keep extended information about the last hostname a user logged in with, which can usually be viewed with /msg NickServ INFO <yournick>. This data is usually kept until the nickname expires and is unregistered. The Rizon IRC network behaves this way. Getting rid of this information requires logging in with a hostname that you do not mind being public.

The behavior of the WHOWAS command is defined in RFC 1459 ยง 4.5.3.
