Database health checker
Evaluates whether entries in the free nsfw.sqlite database still
exist. DNS goes directly to 8.8.8.8 and
1.1.1.1 (raw UDP A-queries built by hand — the OS
resolver cannot interfere; resolver disagreement is shown), then whois is
checked via whois.iana.org → registrar server (TCP/43).
Check one domain
Also runs against any host (resolves + whois). Results persist
in domain_health; latest shown below.
Batch check
What this does: it picks N random domains from the open
database and re-checks each one — a raw DNS A-query straight to
8.8.8.8 and 1.1.1.1 (the OS resolver cannot interfere,
so a disagreement between the two is visible) plus a whois
lookup over TCP/43. It answers one question:
“does this domain still exist?” — alive (it
resolves), parked (NXDOMAIN but still registered),
dead (NXDOMAIN and gone).
The result is stored in domain_health, which is what the
free database ships with — so the download is self-audited. It is
slow (a few hundred ms per domain: two resolvers plus whois each),
and it is a liveness check, not a content scan — the ratings
come from the blocklists. For the same job in bulk, use
run.bat db-health (the Python CLI).
Requires PHP sockets and pdo_sqlite
extensions — the shipped _ini/php.ini enables both; run the site
with serve.bat / serve.sh.
