DNS-over-HTTPS (DoH)

When using the Single Lookup tool, your browser bypasses traditional, insecure networks and queries Cloudflare's massive public DNS resolvers directly via encrypted HTTPS. This means zero latency and maximum privacy.

Backend Scale Processing

When processing massive CSV lists, we offload the heavy networking logic to our cloud architecture. Python workers recursively iterate through your list, preventing rate-limits and producing a clean export file.
