Summary

Zayo Bandwidth

United States of America · AI-generated

transit enterprise fiber bandwidth

The AS handle IFN-NET is held by Zayo Bandwidth.

What it's used for

  • The address space carries static fiber infrastructure, as evidenced by reverse DNS entries like static.indianafiber.net and netnames such as IFN-NET-1 through IFN-NET-6.
  • With 34,304 IPv4 addresses and 39 IPv6 prefixes announced against 18 observed neighbours, the ratio indicates a transit or wholesale bandwidth provider rather than a residential access network.

Notable

  • All registrants in the sample agree with the announcer, consistently listing Zayo Bandwidth for prefixes including 143.55.192.0/19 and 64.184.24.0/21.
  • The operator was formerly known as Intelligent Fiber Network (IFN), a name still reflected in the AS handle and reverse DNS domains.
  • The inventory consists of 38 IPv4 prefixes and 39 IPv6 prefixes, with the largest block being 143.55.192.0/19.

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
