Summary

zColo

United States of America · AI-generated

hosting colo fiber business

The AS handle ZC38-AS2 is held by zColo.

What it's used for

  • The address space carries infrastructure for zColo and its associated FiberNet Telecom Group, evidenced by netnames like ZC38-BLOCK7 and reverse DNS entries pointing to zayo.com and FTGXip.net.
  • The AS announces 4608 IPv4 addresses across 6 prefixes with only 2 observed neighbours, a ratio that suggests a focused hosting or enterprise connectivity role rather than broad transit.

Notable

  • All registrants in the RDAP data are listed as zColo, which aligns directly with the AS holder.
  • Secondary sources identify the operator as FiberNet Telecom Group, a regional NSP, indicating that zColo operates as the technical arm for this telecommunications entity.
  • The inventory consists of six distinct IPv4 blocks, including a /21 and a /22, with no IPv6 prefixes currently announced.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
