AS5374 — AS5374
AS5374 announces 8 IPv4 prefixes covering 72,448 addresses and 0 IPv6 prefixes.
About this network
AS5374 belongs to the United States Department of Defense. It sits inside the DNIC-ASBLK-05120-05376 block, a contiguous range of AS numbers held by the DoD Network Information Center and handed out to individual DoD networks.
What it's used for
- Routing for a US military network. The registry publishes only the block-level DoD registration, not the specific command, base, or program behind this particular AS number.
Notable
- A government network, not a commercial one. Address space here belongs to the DoD rather than to subscribers or hosting customers.
- ARIN records the enclosing DNIC block as registered in 1995, and the low AS number reflects the military's early and large presence on the internet.
Interesting
- The DoD holds AS numbers in whole reserved blocks rather than one at a time, which is why long runs of consecutive low ASNs all resolve to the same Department of Defense registrant.
