if you don't want to use the /ban which indeed does loopup the host first (I usually use /mode rather then /ban)
you need to use /userhost $2 from the event which would trigger the ban. also set %somevar to $2 and %someothervar to the channel name
then, on reply of the /userhost (some raw, can't remember the numeric and mIRC is off atm ;-]) just if (%somevar) && (%someothervar) { mode %someothervar +b $address(%somevar,2) | unset %somevar , %someothervar }
get it?
but like Online says... /ban already does this for you
