Datacenter pattern

Does the network this IP belongs to look like a hosting provider?

What this check is

Every IP address belongs to a network with an owner. This check reads the owner name of the network the request came from and asks a simple question: does this look like a company that rents servers, or like a company that sells internet access to households? People browse from the second kind. Bots are usually hosted on the first.

How to read your result

Warning: The network owner's name resembles a hosting or datacenter provider.
Pass: The owner reads as a consumer or business ISP.
Not available: No network owner was reported for this connection.

Why it matters

It is the cheapest reputation question a site can ask, and it is asked about every request. A hosting-range IP does not get a session banned by itself, but it starts the conversation in debt: everything else the browser does is read in that light. It is also the finding most often responsible when a technically clean browser still scores badly from a VPS or a corporate egress range.

Where this matters most

Across the platforms Blowhorn works with, rated in the platform guide (H = matters a lot, M = contributes, L = no public evidence; tags mark vendor-stated, reported, or inferred evidence):

LinkedIn (M): datacenter egress is a classic checkpoint trigger for a fraud-sensitive login [Reported]
X (H): datacenter IPs are flagged far more aggressively than residential ones [Reported]
Reddit (H): server IPs get much stricter limits and scrutiny [Reported]
Hacker News (M): datacenter-origin accounts attract the spam filter [Inference]

Everywhere else in the set this one rates Low.
