About this network

A company that monitors other people's exposed data, running one /24 that says nothing about itself.

What it's used for

• An identity protection service's network. 256 addresses in one IPv4 prefix, 104.255.33.0/24, one observed BGP neighbour, and no IPv6 announced.

Notable

• The block is netname AIP-104-255-33-0-24, three initials followed by the address and its length.
• The AS handle is the same initials with the AS number appended.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• Putting the address into the netname and the AS number into the handle means both fields are self-describing and neither adds information. That is a registration filed by someone who wanted the records to be unambiguous rather than meaningful, which is a reasonable preference for a business whose product is watching where data leaks.
• A silent reverse zone fits the same instinct. Nothing here volunteers a hostname, a role or a location, so the only way to learn what runs on these addresses is to connect to them.
• One /24 and one upstream is a small footprint for a consumer service, which suggests the monitoring itself runs on rented infrastructure elsewhere and this block is the part with the company's name on it.
