DNS resolvers and caching: definition, mechanism, reproducible checks, and what it means for dedicated static residential operation.

Resolvers turn names into addresses; caches store answers for the record's TTL.

How it works, step by step

  1. 1

    Direct definition

    Resolvers turn names into addresses; caches store answers for the record's TTL.

  2. 2

    How it works with proxies

    With remote DNS (SOCKS5 hostname form), lookups happen at the endpoint.

  3. 3

    Static-residential implication

    Endpoint-side resolution keeps lookups on the profile identity and region.

  4. 4

    Reproducible check

    Resolve a name twice and watch TTLs; then resolve through the endpoint and compare the path.

Failure interpretation

If the reproducible check fails, re-check endpoint values, protocol, and local interception before blaming the target.
