This endpoint is a lightweight router that maps clean paths (e.g. /4/<id>) to your
provider-specific destinations. It enforces allow/block lists, validates IDs, and writes
audit-friendly access logs.
Use stable routes like /4/<id>, /6/<id>, /m4/<id>, /m6/<id> mapped to your downstream endpoints.
Only one prefix match is accepted in allow.txt; block matches override everything. No ambiguity, no surprises.
Log only allowed traffic in a grep-friendly format, with UA capped to a safe max length and CR/LF stripped.
If you operate this endpoint and need to update routing or request an allow-list entry, use your internal process. This public page intentionally keeps configuration details private.
