Our server logs show repeated or unusually heavy traffic from several IP addresses that appear to belong to U.S. government organizations, including the Department of Defense and the Federal Reserve. How can I determine whether these addresses are really government-owned, what might explain the traffic, and whether this is something I should be concerned about?

Before drawing conclusions, verify exactly what you’re seeing in the logs. Include the timestamps, request paths, methods, user agents, response codes, and request volume. An IP lookup can identify the network owner, but it doesn’t prove that the traffic originated from an actual government employee or system. Proxies, compromised devices, scanners, and incorrect geolocation or ownership data can all create misleading results.
It would be very unusual to infer an investigation from this alone. If an organization needed to conduct sensitive activity, the source addresses might not be directly attributable to it, and ordinary automated scanning can come from many kinds of networks. Check the traffic pattern first: repeated requests for common vulnerable files, random paths, high request rates, or identical user agents usually point to automated scanning rather than targeted attention.
Even an IP registered to a government agency could be a misconfigured public service, a shared provider, a proxy, or a compromised host. The registration record is only one clue.
Don’t assume a routing attack based only on unusual IPs. Start by checking the WHOIS or regional Internet registry records, reverse DNS, TLS and HTTP details, and whether the traffic is actually reaching your application through a known proxy or CDN. If the requests are abusive, rate-limit or block the specific behavior, preserve the logs, and contact the network’s abuse or security contact with timestamps and examples. Escalate only if you see clear exploitation attempts, account abuse, or service disruption.
I’m currently seeing the addresses through Nginx access logs, but I haven’t yet reviewed the full request details or confirmed the ownership independently.
