If you’re seeing spikes in traffic from AS396982 in your server logs or security dashboards, you’re not looking at a mysterious threat actor — you’re looking at Google Cloud Platform’s core network. That doesn’t mean the traffic is automatically safe to ignore, though. Because Google Cloud hosts millions of customer workloads, AS396982 is also a common source of abuse traffic, and knowing how to investigate it properly is an important skill for anyone monitoring network security.
What AS396982 Actually Is
AS396982 is an Autonomous System Number registered to Google LLC and operated under the name GOOGLE-CLOUD-PLATFORM, based in the United States. Google manages several ASNs across its infrastructure, including AS15169 for general Google services and AS396982 specifically for Google Cloud Platform. As of mid-2026, the network announces more than 3,600 routed IP prefixes and peers with other autonomous systems as part of the broader internet routing table, with more than 24 million IPv4 addresses under its control.
Why Traffic From This ASN Looks the Way It Does
Understanding the underlying network helps explain some of what you’ll see in logs. Traffic from AS396982 shows little to no day/night variation, which is characteristic of hosting and datacenter networks that operate around the clock rather than following the usage patterns of typical residential or office traffic. This is a normal signature for any major cloud provider — it reflects automated services, backend jobs, and globally distributed customers, not necessarily anything suspicious on its own.
Why This ASN Shows Up in Abuse Reports
Because Google Cloud Platform hosts an enormous number of third-party workloads, AS396982 has a real and measurable presence in abuse tracking systems. Threat intelligence data has recorded tens of thousands of IPs tracked from this Autonomous System, with a significant share currently appearing on blacklists, and separate spam monitoring services note that large networks like Google’s can sometimes be exploited by hackers or spammers looking to carry out malicious activity. This doesn’t mean Google’s infrastructure itself is compromised — it reflects the reality that cloud platforms are attractive to bad actors precisely because they offer cheap, disposable, and reputationally “clean” IP space to launch attacks or scans from, at least until abuse is detected and shut down.
How to Investigate Unusual Traffic From This ASN
If you’re seeing unexpected activity tied to AS396982, a few steps can help you determine whether it’s legitimate or something worth escalating:
- Check the specific IP, not just the ASN. A single ASN can span tens of thousands of IPs used by completely unrelated customers, so reputation and abuse history should be checked at the IP or subnet level rather than assumed for the whole network.
- Cross-reference with blacklist and threat intelligence services. Tools that track abuse reports and blacklist status by IP or ASN can quickly tell you whether a specific address has a documented history of spam, scanning, or attack traffic.
- Look at traffic behavior, not just the source. Repeated login attempts, unusual request patterns, or scraping behavior from a cloud IP are stronger signals of abuse than the ASN itself, since legitimate cloud-hosted services and malicious ones can share the same network origin.
- Review routing and prefix data for anomalies. Monitoring services that track BGP announcements can flag cases where a prefix is announced by more than one Autonomous System simultaneously — a signal sometimes associated with route hijacking — though this is a rarer and more technical scenario than everyday abuse traffic.
Reporting Abuse Tied to This Network
If you determine that traffic from a specific IP within AS396982 is malicious, Google provides direct channels for reporting. For operational or peering-related issues, Google’s network operations center can be reached for peering operational issues, and the company also provides dedicated documentation on its traffic delivery and management practices for network operators dealing with abuse or routing concerns.
Keeping This in Perspective
Seeing AS396982 in your logs isn’t inherently alarming — it’s one of the most active cloud networks in the world, supporting legitimate business traffic at massive scale alongside a smaller volume of abuse that any major cloud provider inevitably attracts. The key is treating the ASN as a starting point for investigation rather than a verdict, and pairing it with IP-level reputation checks and behavioral analysis before deciding how to respond.
Join The Discussion
Tracking traffic tied to major cloud ASNs like AS396982 is a common challenge for security teams, since legitimate and malicious traffic often share the same infrastructure. Have you dealt with unusual or abusive traffic originating from Google Cloud’s network, and if so, what tools or methods helped you separate the noise from a genuine threat? We’d love to hear from anyone working in network security or threat intelligence — what’s your go-to approach when an ASN alone isn’t enough information to act on?
