Re: IBM i Access for Web vs IBM Navigator for i

[Jim Oberholtzer <midrangel@xxxxxxxxxxxxxxxxx>]

Nevertheless, it's a reasonable question.  If there is an attempt to 
communicate with IPV6, then significant CPU cycles may be expended to 
detect and communicate with the network.  It's best to turn off IPV6 
unless it is properly configured and in use. Remember the defaults are 
on, not off.
