AS5852 — DNIC-ASBLK-05800-06055

AS5852 announces 384 IPv4 prefixes covering 506,880 addresses and 4 IPv6 prefixes.

About this network

AS5852 is a US Department of Defense network from the block DNIC-ASBLK-05800-06055, registered to the DoD Network Information Center (DNIC). It is one of the largest ASNs in that block.

What it's used for

• US government / military network operations. The DNIC registration is generic and does not identify a specific command or installation.

Notable

• Government / military space, not a commercial ISP or hosting provider.
• Substantial: roughly 506,000 addresses across some 850 IPv4 prefixes, plus a few IPv6 prefixes. Announcing hundreds of small prefixes under one AS points to a network aggregating many separate sites rather than a single facility.
• Part of the contiguous 5800–6055 block of DoD-held ASNs.
