isp telecom transit

A /15 whose registrant is the registry itself, announced alongside two colleges' own blocks.

What it's used for

  • A regional fibre carrier. 315,648 addresses across 114 IPv4 prefixes, fifty-five IPv6 prefixes, and 227 observed BGP neighbours.

Notable

  • 143.66.0.0/15 is netname NET143, registered to Various Registries (Maintained by ARIN).
  • 150.155.0.0/16 is netname REV-CAYUGA, registered to a community college.
  • 66.109.56.0/21 is registered to a college under a netname that is just its address.
  • The carrier's own blocks are numbered FLNET-15, FLNET-16, FLNET-26, FLNET-31, FLNET-40, FLNET-45, FLNET-49 and FLNET-52.
  • Sampled names are mostly 216-179-63-255.static.firstlight.net; one is isda01.routable.bestweb.net.

Interesting

  • A registrant naming several registries collectively is early address space that predates modern ownership records. Nobody holds it in the modern sense; the registry maintains it because the original allocation structure no longer exists.
  • The numbered FLNET series counts allocations rather than describing them, so the gaps between 15 and 52 are blocks that went elsewhere or were returned.
  • One reverse name still answers under an acquired provider's domain with routable as a label, a distinction that mattered when a customer had to be told which of their addresses reached the internet.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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: 436 networks and 1,771 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.
