📡 Load iptoasn — fast local IP resolution

Replaces the WhoisXML ranges with the iptoasn.com TSVs from data/, then resolves country + ASN across every IP indicator. iptoasn ranges don't overlap, so the range-join is an index seek per IP — thousands/sec.

⚠ Missing in data/: ip2asn-v4.tsv ip2country-v4.tsv. Drop the file(s) in and reload. (.gz is fine too.)

Prefer the shell (fastest for a full re-resolve)? php import-ipdata.php file=data/ip2asn-v4.tsv kind=netblock && php import-ipdata.php file=data/ip2country-v4.tsv kind=geo && php resolve-all.php. This page resolves every unresolved IP from the new data; to also overwrite IPs previously resolved from WhoisXML, run php resolve-all.php after nulling — ask me to add a one-click wipe if you want it.
