All-in-one IPv4 / IPv6 Address Lookup

AS55960（Beijing Guanghuan Xinwang Digital） (Amazon) manages the 52.80.0.0/15 prefix block (approximately 131072 addresses) in the Datacenter / Cloud category. AS55960 independently controls its routing policy, peering relationships and IP allocation — Amazon is directly responsible for traffic to and from addresses in the 52.80.0.0/15 block. The IP 52.81.96.56 resides in China Beijing (timezone Asia/Shanghai); its position within this block determines routing behavior and connectivity characteristics.

The reverse DNS record resolves to ec2-52-81-96-56.cn-north-1.compute.amazonaws.com.cn, which is consistent with the registered provider. This alignment with the registered provider is favorable for email deliverability and system trust scores.

Based on local classification and Spamhaus real-time reputation, no blacklist entries detected, associated risks: datacenter. The Cloud server / datacenter category indicates this IP is part of normal Datacenter / Cloud infrastructure and carries low inherent risk. As a datacenter address, risk-control focus should be on request patterns (user-agent, frequency, behavior chains) rather than the IP alone.

Recommendation: 52.81.96.56 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.
