Summary

Amazon Web Services (AWS GovCloud)

United States · AI-generated

hosting cloud legacy

AWS-GOVCLOUD is the Amazon Web Services autonomous system serving AWS GovCloud, the isolated AWS regions built for US government workloads and regulated data.

What it's used for

  • Public-cloud compute, storage and networking in the us-gov-west-1 and us-gov-east-1 regions. Reverse DNS across the announced space resolves to ec2-IP-ADDR.us-gov-west-1.compute.amazonaws.com and the matching us-gov-east-1 zone, plus GovCloud Route 53 nameservers (awsdns-us-gov domains).
  • It announces a large, scattered inventory (over a hundred IPv4 prefixes and a similar number of IPv6 prefixes) drawn from many different Amazon blocks.

Notable

  • Despite the name, this is cloud hosting infrastructure operated by Amazon, not a government-run network. The customers are US federal, state and local agencies and their contractors, but the addresses belong to AWS.
  • The RIR object is held under an Amazon corporate entity rather than a US government body, and the space should be treated as commercial cloud, not agency, address space.

Interesting

  • GovCloud regions are operationally partitioned from commercial AWS, yet they share the same AS number here, so a lookup on this ASN mixes both the us-gov-east-1 and us-gov-west-1 footprints.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,771 prefixes, as published 2026-10-15. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
