All-in-one IPv4 / IPv6 Address Lookup

AS396982（Google LLC） (Google) manages the 104.155.224.0/20 prefix block (approximately 4096 addresses) in the Datacenter / Cloud category. AS396982 independently controls its routing policy, peering relationships and IP allocation — Google is directly responsible for traffic to and from addresses in the 104.155.224.0/20 block. The IP 104.155.236.61 resides in China Taiwan Taipei (timezone Asia/Taipei); its position within this block determines routing behavior and connectivity characteristics.

The reverse DNS record resolves to 61.236.155.104.bc.googleusercontent.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: 104.155.236.61 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.
