All-in-one IPv4 / IPv6 Address Lookup

AS14618（Amazon.com, Inc.） (Amazon) manages the 3.227.0.0/16 prefix block (approximately 65536 addresses) in the Datacenter / Cloud category. AWS Asia-Pacific region, covering EC2, Lambda, etc.; some IPs are used by VPN/proxy services. The IP 3.227.248.201 resides in United States Virginia Ashburn (timezone America/New_York); its position within this block determines routing behavior and connectivity characteristics.

The reverse DNS record resolves to ec2-3-227-248-201.compute-1.amazonaws.com, which is consistent with the registered provider. This alignment with the registered provider is favorable for email deliverability and system trust scores.

Spamhaus has listed this IP (XBL: 僵尸网络 / 被攻陷主机), which suggests it has been involved in spam or compromised activity. While a listing does not guarantee ongoing abuse, it can impact deliverability and trust score. As a datacenter address, risk-control focus should be on request patterns (user-agent, frequency, behavior chains) rather than the IP alone.

Recommendation: 3.227.248.201 is a datacenter/cloud IP — it may host legitimate services (APIs, CDNs, bots) or serve as an attack vector. Evaluate each request context: allow known API integrations, challenge or block unknown automated traffic, and never trust the client-reported IP for geo-based decisions.

Datacenter IPs are frequently used for legitimate API integrations, automated monitoring and infrastructure tasks — evaluate each request context before blocking. If you need to distinguish automation from real-user traffic, focus on request headers (User-Agent, Accept) and behavioral patterns rather than IP reputation alone.
