We operate a sophisticated domain intelligence infrastructure to **collect**, **process** and **analyze** (very) large amounts of data. We make this data available to our customers and threat intelligence partners in real-time and as daily downloadable feeds.

Introduction

Welcome to [dns0.eu](https://dns0.eu) official documentation.

Most malicious domains are registered from a few days to only a few seconds before becoming active, making those domains a very valuable subset of domains to analyze when looking for future malicious activity.

Newly Registered Domains (NRD)

While NRD focuses on the first appearance of a domain name in a registry (i.e. the domain registration), NOD focuses on the first time a domain name is observed in the DNS. Newly registered domains are sometimes purposely kept unconfigured for a period of time to avoid detection, making this data another valuable subset of domains to analyze when looking for malicious activity.

Newly Observed Domains (NOD)

NOH focuses on the first time a hostname is observed in the DNS and can help uncover malicious activity at the subdomain level.

Newly Observed Hostnames (NOH)

Domains are sometimes warmed up — often showing the appearance of legit activity — to avoid detection before suddenly turning malicious, making this data a very valuable subset of domains to analyze when looking for malicious activity.

Newly Active Domains (NAD)

Newly Active Hostnames (NAH)

Nearly all malicious domains get issued a certificate — either manually or automatically — very early in their lifecycle and before becoming active. Certificates also contain valuable pieces of information and patterns when investigating malicious activity.
