About this network

DNIC-ASBLK-27032-27159 is held by the United States Department of Defense (DoD).

What it's used for

• The address space carries military and defense infrastructure, evidenced by reverse DNS entries such as reverse.akamai.csd.disa.mil and usmc.mil, and netnames like SRFYOKONET2 and DISN-IP-UC-1-0.
• With 35,584 IPv4 addresses announced across 84 prefixes and 33 observed neighbours, the ratio suggests a large internal corporate estate with significant internal segmentation rather than a transit provider.

Notable

• Registrants include the DoD Network Information Center and the Navy Network Information Center (NNIC), aligning with the DoD holder.
• The inventory is finely subdivided into numerous /22 and /23 blocks, consistent with site-by-site segmentation for a large federal agency.
