Cautionary Risk
IP 213.209.157.216 is a medium-risk German address with a substantial abuse history, primarily linked to email spam activity detected by automated honeypot sensors. With 1,498 total reports concentrated in November and December 2025, this address presents a moderate threat to exposed mail services, though its recent activity frequency of zero suggests diminished current engagement.
The IP originates from Germany within the AS208485 network operated by Moon Dc, and automated honeypot sensors logged all 20 recent threat reports attributing activity exclusively to email spam. The 55% confidence score and 5/10 threat level reflect a pattern consistent with mass-distribution spam operations rather than targeted attacks. Despite the high cumulative report count, the zero activity frequency metric indicates no detected malicious behavior in the immediate recent period, suggesting the address may have been contained, blocked at the network level, or temporarily retired from active operations.
Email spam originating from this address poses concrete risks to organizations with exposed SMTP servers. Such activity typically involves high-volume distribution of unsolicited messages that may contain phishing links, malware payloads or fraudulent content, potentially harming recipients and damaging the reputation of any mail server that relays this traffic. For organizations receiving connections from this IP, the spam history indicates it should be treated with suspicion and evaluated against established email authentication standards before accepting or relaying any correspondence.
Site operators should implement a combination of reactive and preventive controls: configure mail servers to enforce SPF, DKIM and DMARC authentication to reject unauthorized sending from this address, add 213.209.157.216 to server-level blocklists, and monitor logs for any new connections originating from this IP. Tools such as fail2ban can automate the detection and blocking of suspicious SMTP patterns. Ensuring mail relay policies require valid sender authentication will prevent any potential abuse of your infrastructure for spam distribution.
