Unclassified ARIN
Summary
D4 Networks
isp hosting business
The registrant name carries a city on the end, so the company is filed twice under two slightly different identities.
What it's used for
- A regional provider's network. 768 IPv4 addresses across two prefixes, three IPv6 prefixes, and three observed BGP neighbours.
Notable
66.85.94.0/23carriesD4-NET, registered to the company's plain legal name.66.85.92.0/24carriesD4-NETWORKS-DALLAS, registered toD4 Networks L.L.C. - Dallas.- The three IPv6 announcements are
2602:f38e:1::/48,2602:f38e:2::/48and2602:f38e:4::/48. - Six addresses were queried for reverse DNS and none returned a name.
Interesting
- Appending a location to the registrant, rather than to the netname alone, creates a second organisation in the registry that is not a second organisation in the world. Anyone matching address space to companies by exact name gets two, and anyone matching loosely risks merging companies that really are distinct.
- The IPv6 numbers skip one. Three end-site blocks numbered one, two and four means the third was either used and withdrawn, or reserved for a site that never opened. Both are common; neither is recorded anywhere a stranger can see.
- A provider holding IPv6 and announcing three separate end-site blocks has thought about per-site numbering, which puts it ahead of most networks its size in this range.
- Three upstreams for 768 addresses is generous, and the right trade for a business whose product is other people staying online.

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 2026-10-15, 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 1,781 prefixes, as published 2026-10-16. 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.
