Summary

FirstLight Fiber

United States of America · AI-generated

fiber colocation business northeast

COLOSPACE is the AS handle for FirstLight Fiber, Inc., a fiber optic network operator in the Northeastern United States.

What it's used for

  • The address space carries static IP addresses for business and colocation services, evidenced by reverse DNS entries like static.firstlight.net and static.rev.colospace.com, and netnames such as FLNET-28 and PNAP-BSN-COLOSP-RM-01.
  • With 32,256 IPv4 addresses announced across 15 prefixes and only 3 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.

Notable

  • Registrants include FirstLight Networks, LLC, ColoSpace, Inc., Media 3 Technologies, LLC, Cape Cod Computer, Inc., and PF IPV4 Borrower, LLC, reflecting a mix of owned infrastructure and acquired or leased space.
  • ColoSpace, a New England data center and managed IT services provider, was acquired by FirstLight Fiber on December 10, 2019, explaining the presence of colospace.com reverse DNS and PNAP netnames within this AS.
  • The inventory consists of 15 IPv4 prefixes with no IPv6 prefixes announced, showing a purely IPv4 footprint.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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 1,778 prefixes, as published 2026-10-20. 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.
