About this network

TW-ASN-01 — the network of Boldyn Networks Transit US LLC, formerly Transit Wireless, the neutral-host operator that built and runs wireless connectivity throughout the New York City subway.

What it's used for

• Infrastructure and backhaul for the distributed antenna system and Wi-Fi network across the MTA's subway stations and tunnels.
• A carrier-neutral platform: AT&T, Verizon, and T-Mobile connect their own equipment into the same shared physical network rather than each building their own.

Notable

• Infrastructure address space, not an eyeball network — a handful of /24s supporting network operations, not a pool of subscriber addresses.
• Transit Wireless was rebranded under Boldyn Networks (formerly BAI Communications), which also runs neutral-host transit networks elsewhere.

Interesting

• ARIN registered AS5008 in 2015, so this low number is a modern reassignment and carries no early-internet pedigree.
