DNS Cache

Temporary storage of Stripchat DNS answers on devices and resolvers.

Definition​

A DNS cache stores recently resolved DNS records locally (on your device) or on recursive resolvers. Entries include a time-to-live (TTL) after which they expire.

Why it matters​

  • Speeds up access: Cached IPs avoid repeating the full lookup, improving page load time.
  • Source of stale data: If Stripchat updates IPs, outdated cache entries can keep pointing to dead servers or block pages.
  • Censorship persistence: Poisoned cache entries may stick until flushed, so unblocking requires clearing caches too.

Tips​

  1. Flush OS caches after changing DNS servers or when Stripchat fails while other sites work.
  2. Lower TTL values on self-hosted mirrors so changes propagate quickly.
  3. Inspect resolver caches (rndc dumpdb -cache) to verify which entries are served to users.
