Summary

Boldyn Networks Transit US LLC

United States · AI-generated

enterprise legacy

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.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 447 networks and 1,843 prefixes, as published 2026-11-02. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
