Rails - Mar 2006 - Accessing Helperfunctions from the Controller

Hi there,

how can i access a helper from within my controller? :)
Since i got a helper that serves my views with certain stuff, but at 
some point i need this helper in my controller for gathering data.


since "helper :ipv4addr" includes me ipv4addr_helper.rb but not its 
functions.. or at least i don''t know how to acces these functions :)

Thanks in advance!
