Newly Observed Domains (NOD)
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.
This can be extremely helpful to uncover newly registered domains for ccTLDs
whose registries chose not to disclose registration times (.de, .es, .eu
and more).
