About this network

A US Department of Defense network from the block DNIC-ASBLK-05800-06055, registered to the DoD Network Information Center (DNIC). Its two large prefixes are registered to the Navy Network Information Center (NNIC).

What it's used for

• US Navy shore-side networking. Its main blocks carry the netnames CNET-PCOLA (160.125.0.0/16) and CNET-SDIEGO (160.128.192.0/18), pointing at Navy education and training sites around Pensacola, Florida and San Diego, California.
• Roughly 82,000 IPv4 addresses in total, dominated by that single legacy /16.

Notable

• A government / DoD network, not a commercial ISP or host.
• The registration is one of the few in the DNIC block that names a service rather than just "Department of Defense" — the Navy ran its own NIC, and the netnames survive from that era.
• Part of a contiguous run of ASNs (5800–6055) held by the DoD Network Information Center.
