⁠TelcoSec PSTN/ADSL Cyber Range — DNS (Lab Resolver)

A lightweight dnsmasq resolver providing internal name resolution across the lab's management network — so simulated CPEs, the ACS, and RADIUS/BNG/LNS components can address each other by hostname within the emulated ISP.

Part of the TelcoSec PSTN/ADSL Cyber Range — a 16-container, 100% software-based telecom security lab modeling a realistic wholesale ISP (copper-line impairments, PPPoE, RADIUS/AAA, L2TP wholesale roaming, TR-069/CWMP). Built for the TelcoSec Telecom Security Academy.

⚠️ Intentionally vulnerable. Ships plaintext PAP/crackable MS-CHAPv2, an unauthenticated MongoDB backend, and unencrypted TR-069 by design, for red-team training. Do not deploy outside an isolated lab network.
