about

nx_dht_ping.nx -- LIVE DHT reachability probe (X-TORRENT-LIVE-002 R4b). Resolves real BEP-5 bootstrap nodes and KRPC-pings them over UDP:6881; GREEN if any returns a valid response dict. This is the EMPIRICAL test of whether the DHT is reachable from here, or whether the ISP/network blocks UDP:6881 (the same class of blocking that already kills UDP tracker ports :1337/:6969). Composes nx_dht (KRPC build/parse) + nx_dns_a (resolve) + raw UDP syscalls. NO external resolver. license_tier: ORIGINAL layer: peer-discovery probe module: nishi-core.torrent.dht_ping depends: nishi-core.torrent.dht, nishi-core.dns_a
