Summary

GFT (formerly Gannett Fleming)

United States of America · AI-generated

business engineering corporate us

GFNET-AS01 is held by Gannett Fleming, Inc., a major architecture, engineering, and design firm.

What it's used for

  • The space carries corporate infrastructure for a professional services firm, as indicated by the registrant Level 3 Parent, LLC for the netname LVLT-ORG-216-174.
  • The AS announces a single IPv4 prefix, 216.174.25.0/24, comprising 256 addresses, with 2 observed neighbours, suggesting a small, dedicated corporate uplink rather than a transit or access network.

Notable

  • The registrant Level 3 Parent, LLC differs from the announcer Gannett Fleming, Inc., indicating the address space is leased from a larger carrier.
  • Gannett Fleming merged with TranSystems and other acquired businesses to rebrand as GFT, a combined national platform for engineering and design services.
  • The inventory consists of a single /24 block with no IPv6 prefixes, reflecting a minimal footprint typical of a corporate office network.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
