About this network

The AS handle DNIC-ASBLK-27032-27159 is held by DoD Network Information Center.

What it's used for

• The address space carries Department of Defense network operations, evidenced by netnames such as DISA-CSD-101, DISA-EUROPE, and DNIC-NET-214, and reverse DNS entries pointing to socom.mil and disa.mil domains.
• The AS announces 33,792 IPv4 addresses across 53 prefixes and 3 IPv6 prefixes, while maintaining 25 observed neighbours; this ratio of substantial address inventory against a moderate peer count indicates a large internal government network rather than a transit provider.

Notable

• All registrants in the evidence pack are consistently listed as DoD Network Information Center, aligning perfectly with the AS holder identity.
• The address inventory is finely subdivided into numerous /22, /23, and /24 blocks, reflecting site-by-site segmentation typical of a large corporate or government estate.
• The presence of specific netnames like DISA-EUROPE suggests the space supports geographically distributed defense infrastructure.
