It's O(n) as previously stated.
Looking something up in a huntgroup means iterating over every member
of the linked list (worst case) and evaluating the condition each time
to see if it matched.

There's no hashing or treeing or anything fancy, just a plain linked list.
But people get really horny about it like it's *the* ultimate super
efficient NAS categorisation mechanism. It's not, it's shit, it needs
to go away.
Using the client xlat is significantly more efficient. There's also the
getclient xlat which allows client lookups using arbitrary IP addresses.
