Summary

hosting business infrastructure
Fifty-two thousand addresses, sixty-four announced prefixes, and one observed neighbour.
What it's used for
- A colocation provider's network in the United States. 52,480 addresses across thirty-one IPv4 prefixes, thirty-three IPv6 prefixes, and one observed BGP neighbour.
Notable
- Netnames run
ZC38-BLOCK2,ZC38-BLOCK3,ZC38-BLOCK4,ZC38-BLOCK8throughZC38-BLOCK12. - The same block number covers several separate announcements:
ZC38-BLOCK3holds both a /20 and a /22,ZC38-BLOCK11andZC38-BLOCK12each hold two. - Sampled names are
cust-108-60-207-255.corexchange.com, with some carrying a site code:cust-67-211-43-254.dllstx01.corexchange.com. - One address answers under a different domain entirely,
zcd.bissinc.us. - One prefix's registry lookup failed, so nothing is known about its registration here.
Interesting
- A single neighbour for a network this size means everything reaches the internet through one parent company. The colocation business was acquired by its upstream, and the routing shows the result: a large, well-populated network with exactly one door.
- The block numbers are the acquisition ledger. Each is one allocation, later cut into several routes, so counting distinct numbers gives the number of times the company obtained space and counting prefixes gives the number of times it needed to steer traffic separately.
- Site codes appear in some reverse names and not others, which is two generations of zone tooling running side by side.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 447 networks and 1,852 prefixes, as published 2026-10-27. 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.
