transit legacy

PACKETFABRIC-AS4556 — PacketFabric, Inc., a Network-as-a-Service (NaaS) carrier offering software-defined private connectivity: point-to-point circuits, virtual cross-connects, and on-ramps into the major public clouds.

What it's used for

  • Carrier-grade transport and IP transit sold to enterprises and other networks, provisioned on demand through an API/portal rather than through traditional circuit ordering.
  • Announces around 12,000 IPv4 addresses, modest for a carrier because most of its business is layer-2 transport for other people's addresses.

Notable

  • A transit/backbone network, not an eyeball or hosting AS.
  • Despite the low number, ARIN registered AS4556 to PacketFabric in 2017 — this is a reissued ASN and carries no early-internet pedigree.

Interesting

  • PacketFabric merged with Unitas Global in 2023, combining an automated private-transport fabric with Unitas' managed internet and edge business.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
