Summary
FirstLight Fiber
isp telecom business infrastructure
Three company names across three fields, and netnames numbered by allocation rather than address.
What it's used for
- A regional fibre carrier. Thirteen IPv4 prefixes announced from the United States, no IPv6, and two observed BGP neighbours.
Notable
- The AS handle names one company, the holder record names a second, and every registrant names a third, all versions of the same business at different points in its history.
- Netnames are the carrier's initials with a two digit counter, and each counter covers several blocks that share a range, so the numbering tracks allocations rather than routes.
- One block belongs to a state university system under a netname that simply says subnets.
- Every one of the eighteen sampled addresses answered, all in the same form: the address with dashes, the word static, and the carrier's domain.
- Twelve thousand addresses across thirteen routes.
Interesting
- Complete and uniform reverse DNS across every sampled block is rare in this range and is what a carrier's provisioning should look like. One rule, applied everywhere, generated from the address.
- Marking everything static is a business statement: these are fixed connections sold to organisations, not a consumer pool, and receivers that score mail by reverse name will treat them accordingly.
- Three names for one company across three fields is the ordinary residue of acquisition. Nothing here is wrong; it just means no single field identifies the operator on its own.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation
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 1,784 prefixes, as published 2026-10-19. 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.
