/**
 * An Updater to set the current IP addresses via
 * the Bytecamp DDNS service.
 *
 * Configuration (environment variables):
 *   - `BYTECAMP_USER`
 *   - `BYTECAMP_PASS`
 *
 *    All environment variables can be read from a file.
 *    The main purpose is to support docker secrets.
 *    For this to work just add `_FILE` suffix.
 *    (E.g. `BYTECAMP_PASS` -> `BYTECAMP_PASS_FILE`)
