Hi there, while trying to understand the algorithm employed in the `find_best_view` function in the geoip module, I started wondering whether this line is in there intentionally: https://gitlab.labs.nic.cz/knot/knot-dns/blob/4015475b0d3e11c0bd6fcac8aceb6… I am still trying to understand how this works with the actual geo data, but here is a test case using the subnet mode that yields slightly surprising results: Using a geoip config like this for zone example.com: bar.example.com: - net: 127.0.0.0/8 A: 9.9.9.9 - net: 192.0.0.0/8 A: 1.1.1.1 - net: 192.168.0.0/16 A: 4.4.4.4 - net: 192.168.1.0/24 A: 8.8.8.8 If I query bar.example.com from 192.168.1.X, I get 4.4.4.4, which is suprising because it is neither the most nor the least specific item. The binary search returns the most specific one (8.8.8.8), which is sort of what I would expect. However, above line immediately takes the `prev` item without checking for `view_strictly_in_view`. Without the above line, the whole function returns the most specific item, as I would expect. Please note that this is mostly an intuition atm, as I have not yet had the time to set up a similar test case for real geo data (which uses the same algorithm). But I figured that someone more familiar with the code might have enough context to tell whether this is correct or not or what a suitable fix might look like. Thanks a bunch, Conrad
