Waziristan (N. and S.) are two agencies in the Federally Administered Tribal Areas of Pakistan.
This interactive map isn’t 100% (and the story that goes with it is so-so) but it does show you where things are and who some of the players are.

Important to realise: these are very rugged, mountainous areas. The border Afghan-Pak is ill-defined (Durand line) and porous and hard to patrol, with the same tribes arrayed across the border without regard to the white man’s governments and preferences. The mountains divide up the tribes so that someone who lives in one valley may never interact (except over rifle sights) with a villager across a mountain but only three miles away.
The best prep for going there, actually, is to read Kipling. (The stories and novels, more than the poetry). Nothing important has changed in these hundred years.
