About this network

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

• 66.43.16.0/22 carries the netname MYFAMILY and is registered to Myfamily.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.
