When I start bridgedb with loglevel INFO, it says things like ``` Dec 24 19:58:54 [INFO] by location set: 59 50 56 50 Dec 24 19:58:54 [INFO] by category set: 40 ``` and then when I hit if from an IP in the 'category set', it says ``` Dec 24 19:59:17 [INFO] area is 87.236.194 Dec 24 19:59:17 [INFO] --------------------------------- Dec 24 19:59:17 [INFO] category<1970>87.236.194 Dec 24 19:59:17 [INFO] Replying to web request from 87.236.194.158. Parameters were {} ``` So I assume that means the category set is the same as the set of bridges it gives out when an IP from the bulk-exitlist file asks. But the assignments.log gives no hint about which bridges are in this category set. Is it a subset of each ring? Or some other set that never gets logged in the assignments list? Confusing.
