Unclassified ARIN
Summary

business enterprise media
The block is still registered to the name the company traded under before it renamed itself.
What it's used for
- A genealogy service's network. 1,024 addresses in a single IPv4 prefix, with two observed BGP neighbours and no IPv6 announced.
Notable
66.43.16.0/22carries the netnameMYFAMILYand is registered toMyfamily.com, Inc.- The AS name is the current brand, written with an extra full stop after the domain suffix.
- The contact on the block is a domain registration function rather than a network one.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- Two names for one company sit in the same record, and the older one is on the part that is harder to change. Renaming a business means renaming the website, the signage and the share listing; renaming an address block means filing a form nobody is paid to file, so the registry lags by however long the company has existed under its new name.
- Pointing the contact at whoever handles domain registrations rather than at network operations is a common arrangement in companies where the internet presence is a marketing asset first. It works until somebody needs to report a routing problem.
- A service holding family trees and genetic data has an unusually strong reason to publish nothing about its infrastructure, and nothing here is published.
- Two upstreams and a single block is a small announced footprint for a business of this size, which points at the customer-facing service living somewhere else entirely.

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 2026-10-15, 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 1,782 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.
