Summary
Delta Dental Plan of Michigan
finance business enterprise
The one answering address is a nameserver, and the netname matches nothing in the company's name.
What it's used for
- A dental insurer's network. A single IPv4
/22announced from the United States, no IPv6, and three observed BGP neighbours.
Notable
- The netname is six letters that share nothing with the registrant, the AS handle or the company's domain, so its meaning is lost outside whoever typed it.
- The single answering address names itself as a nameserver, with the company initials, a site code and a counter before the corporate domain.
- The AS handle is the company's four initials with a counter.
- Three addresses were queried for reverse DNS and one returned a name.
- One thousand and twenty-four addresses behind three upstreams.
Interesting
- Naming a nameserver in reverse DNS is ordinary and still worth noting: it identifies a machine whose job is to answer queries from anyone, and the counter says there is at least one more.
- Three upstreams for one block is a lot of redundancy for an insurer's public edge, which suggests claims traffic that cannot pause while a provider is repaired.
- A netname nobody can decode is the most common kind of registry entry in this range. It was meaningful to one person on one day, and it will outlive the reason.

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 2026-10-27, 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: 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.
