Can a supplier fake a report?

They can fake a screenshot. A report generated by a checker on the actual addresses cannot be faked without controlling the addresses.

What is a good pool grade?

A or B with a clear ASN mix. An A made of one datacenter ASN is not a good pool — it is a well-labelled bad one.

How to read an IP pool report

A pool report is not a score to admire — it is a document you use to argue with a supplier. Here is what each part means.

Verdict mix

The first thing to look at is the mix, not the average. A pool with 60% residential and 40% hosting is not "60% good": every second address is the kind platforms weight heaviest.

By country

Compare the country mix with what the vendor promised. A "German pool" that is 80% one datacenter country is a resold range, not a local residential pool.

Networks to look at

This table groups addresses by ASN and counts how many were flagged. One hosting ASN carrying most of the pool is the clearest sign of resold datacenter space.

Confidence, not certainty

Every verdict has a confidence level and evidence. Treat a 60% CDN verdict as "worth a manual look", and a Tor or DROP hit as a hard stop.

Turn it into a message

Quote the ASN and the flagged count, not adjectives.
Attach the report link and the sample list.
Ask one concrete question: "which of these addresses are static, and in which ASN?"
