ASN summary
How to read the scale of AS1590
DNIC-ASBLK-01550-01601 - United States Department of Defense (DoD) currently reports 34 prefixes and 1 upstream, downstream, or peer relationships. These counts describe the current dataset; they do not by themselves prove network quality, reach, or service use.
What can an ASN page answer?
An ASN page shows the public organization label, country or region, BGP prefixes, and available peer and upstream relationships. It adds network context but cannot confirm a website host, physical facility, security status, or service quality.
How should you read the organization and region fields?
DNIC-ASBLK-01550-01601 - United States Department of Defense (DoD) is currently associated with an unknown region. These values come from public network sources and are useful lookup clues; an organization label, registration region, and actual service location may differ.
How should you verify the AS1590 result?
The page shows ASN data returned by the current upstream query; interpret it with the update time. Open representative IP pages from the same network and compare prefixes, source labels, and query times. Verify operator or service claims with the relevant registry or network operator.
