High Risk
IP 217.160.24.45 is a high-risk German address associated with VoIP fraud activity, presenting a threat level of 8/10 based on 422 abuse reports and sustained engagement with honeypot detection systems.
Registered to IONOS SE under ASN AS8560 in Germany, this IP address generated reports exclusively through 20 automated honeypot sensors during May 2026. The activity frequency score of 8/10 and a confidence score of 92% indicate persistent, targeted behavior rather than opportunistic scanning. Of the reported threat categories, VoIP fraud dominates with 20 confirmations, while general hacking activity contributed 2 additional reports. The volume and consistency of detection strongly support treating this address as a confirmed threat source.
VoIP fraud exploits phone systems to route unauthorized calls, frequently targeting premium-rate or international numbers to generate direct revenue. The detected stream manipulation patterns suggest this address is actively probing session establishment parameters to initiate or maintain fraudulent call connections. For organizations operating SIP-based phone infrastructure, this activity translates to direct financial exposure through toll fraud, unauthorized routing charges, and resource consumption on phone systems.
Site operators should implement call authentication mechanisms such as STIR/SHAKEN protocols, establish call pattern monitoring with alerting thresholds for premium-rate and international destinations, and restrict outbound dialing to verified routes. Deploying automated authentication hardening tools such as fail2ban can block repeated connection attempts from this address. Blocking the IP at the network perimeter based on existing abuse reports provides an immediate defensive layer while longer-term telephony security measures are implemented.
