Summary

Zayo

United States of America · AI-generated

transit enterprise fiber backbone

The AS handle 360NETWORKS- is held by Zayo.

What it's used for

  • The address space is registered under netnames 360NETWORKS-BLK-1 and 360NETWORKS-BLK-2, with all registrants identified as Zayo Bandwidth.
  • The AS announces 69,376 IPv4 addresses across 66 prefixes and 1 IPv6 prefix, while maintaining only 4 observed neighbours. This high address-to-neighbour ratio indicates a transit or backbone role rather than an access network.

Notable

  • All sampled registrants align with the announcer, consistently listing Zayo Bandwidth.
  • Zayo Group is an American communications company that provides fiber optic infrastructure and network services.
  • The inventory consists of large blocks, including a /19 and multiple /20s and /21s, primarily within the 66.62.0.0/16 and 216.166.0.0/16 ranges.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-28, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
