Summary
DedFiberCo
hosting isp business
Fifteen answering names, and not one of them belongs to either company in the registry.
What it's used for
- A provider's network. Twenty-three IPv4 prefixes and one IPv6 prefix announced from the United States, sixteen thousand one hundred and twenty-eight addresses, through three observed BGP neighbours.
Notable
- The AS handle spells the company out in three full words. The holder line gives a run-together short form of those same three, so the two fields describe one company at two lengths.
- Most blocks carry that short form as their netname, meaning the registry followed the holder rather than the handle.
- Three blocks belong to a second company, under a netname of its full name and corporate form, hyphenated.
- Fifteen of eighteen queried addresses answered, every one on a single domain belonging to a third company, and none on either registrant's.
- All fifteen share one template: the address with hyphens, then the word host, then that third domain.
Interesting
- A reverse zone owned by a company that appears nowhere in the registry is the signature of colocation. One company announces the space, another holds it on paper, a third runs the machines that answer.
- Twenty-three blocks and exactly one naming template says the answering side is a single automated platform, whatever the registry says about who owns which piece.

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 2026-10-14, 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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
