Unclassified ARIN
Summary
US Department of Defense
government military research legacy
A US Department of Defense network from the block DNIC-ASBLK-05800-06055,
registered to the DoD Network Information Center (DNIC). Its only current
announcement is an IPv6 /48 from DREN address space.
What it's used for
- US government / military networking. The single prefix it announces (
2001:480:31::/48) sits inside2001:480::/32, the block registered asDREN-V6to the High Performance Computing Modernization Program — so this is a site on the Defense Research and Engineering Network. - The generic DNIC block registration does not name the specific site or unit.
Notable
- A government / DoD network, not a commercial ISP or host.
- Unusually, it announces no IPv4 at all — its routing presence is IPv6-only. DREN is a long-standing early IPv6 adopter in the US government, so an IPv6-only DREN site is less surprising here than it would be almost anywhere else.
- Sibling DREN-connected ASNs in the same DoD block include [AS5957](https://asn.ipinfo.app/AS5957) and [AS5980](https://asn.ipinfo.app/AS5980).
