Summary

FirstLight Fiber, Inc.

United States · AI-generated

isp telecom infrastructure

Most of the blocks it announces are registered to its customers: two colleges, a borough, and a rival carrier.

What it's used for

  • A regional fibre carrier's network. 6,656 addresses across seven IPv4 prefixes and 45 IPv6 prefixes, with 22 observed BGP neighbours.

Notable

  • 70.32.48.0/20 is registered to Westminster College with netname WESTMINSTERIP4, 166.66.202.0/24 to Millersville University of Pennsylvania, and 174.34.252.0/24 to Borough of State College with netname BSC-204.
  • 38.87.49.0/24 carries COGENT-A, registered to Cogent Communications, LLC.
  • Only two blocks are the carrier's own, netnames FLNET-36 and FLNET-23, registered to FirstLight Networks, LLC rather than the name on the AS handle.
  • The AS first appeared in routing on 2012-06-22.

Interesting

  • A carrier whose routing table is mostly other people's address space is doing exactly what a regional fibre operator sells: institutions that own portable addresses keep them and change who announces them. The customer list is legible from the registry alone.
  • One of those customers is another carrier's block, which is what happens when a competitor's circuit is replaced but the addresses on the equipment behind it are not.
  • The IPv6 side runs a doubling ladder from 2607:3180::/47 up to /41, forty-five announcements from a handful of allocations, against seven IPv4 prefixes. The newer protocol is where this network's growth has been recorded.

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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
