IP Prefix list

Block “IP Prefix list” returns special LPM (Longest Prefix Match) object which can be used only for membership testing. Because of that this block only works with operator “in”. Returned object represents prefix list defined by user in appropriate menu section. More about IP Prefix lists is in chapter: IP Prefix lists.

Changed in 3.4.0 in prior versions this block returned iterable structure.
