Summary
H5 Data Centers
hosting colocation datacenter
The AS handle HCDL-DENVER-DATA-CENTER is held by H5 Data Centers.
What it's used for
- The address space carries colocation and data center infrastructure, evidenced by reverse DNS entries such as
ip-69-166-106-128.den.h5datacenters.comandip-207-188-8-128.sea.h5datacenters.com. - The network announces 3328 IPv4 addresses across 10 prefixes and 1 IPv6 prefix, with 7 observed neighbours, indicating a hosting provider role rather than a transit carrier.
Notable
- Registrants for the majority of prefixes are listed as H5 Data Centers, while the prefix 64.129.78.0/24 is registered to Level 3 Parent, LLC with netname TWTC-NETBLK-11.
- The address inventory is subdivided into multiple /23 and /24 blocks, reflecting a multi-site data center estate with locations identified in rDNS as den, sea, qcy, cle, and nyc.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-20, 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: 442 networks and 1,778 prefixes, as published 2026-10-20. 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.
