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 address space is associated with the Joint Training Enterprise Network (JTEN) — reverse DNS in its range resolves under jten.mil.

What it's used for

• Networking for joint training. JTEN is the network underpinning the Joint National Training Capability, carrying live, virtual and constructive training exercises between combatant commands, services and training sites. The same domain fronts Joint Knowledge Online, the DoD's joint online-training portal.
• It announces 199.112.128.0/20 from DNIC space — roughly 4,000 IPv4 addresses.

Notable

• A government / DoD network, not a commercial ISP or host.
• Training networks are a distinct slice of DoD networking: they must interconnect many organisations for an exercise and then stand back down, which is why they get their own AS rather than riding on an operational one.
