fiber transit enterprise infrastructure

CROWNCASTLE-AS33132 is operated by Zayo Bandwidth, following the acquisition of Crown Castle's fiber business.

What it's used for

  • The address space carries enterprise fiber and metro connectivity, evidenced by netnames such as ZAYO-CCF-170-55-0-0 and ZAYO-CCF-69-80-64-0.
  • With 129,792 IPv4 addresses and 90 observed neighbours, the ratio indicates a transit and wholesale fiber network rather than a residential access provider.

Notable

  • Registrants for the majority of prefixes are Zayo Bandwidth, while the largest block 167.93.0.0/17 is registered to School District of Volusia County under netname VOLUSIA.
  • Zayo completed the acquisition of Crown Castle's fiber solutions business, which explains the transition from the CROWNCASTLE handle to Zayo's operational control.
  • The inventory consists of 101 IPv4 prefixes and 38 IPv6 prefixes, with the largest IPv4 block being 167.93.0.0/17.

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 1,775 prefixes, as published 2026-10-11. 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.
