Unclassified RIPE
Summary
E-Zorg
healthcare business netherlands
E-ZORG is operated by E-Zorg B.V.
What it's used for
- The address space carries corporate infrastructure for a Dutch healthcare provider, as indicated by the registrant
E-Zorg B.V.and netnamesNL-E-ZORG-20111215andNL-E-ZORG-20190930. - The AS announces 3072 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 47 observed neighbours. This ratio of limited address space against a high number of peering partners suggests a transit or interconnection-heavy role rather than a large-scale access network.
- Traffic from this AS consists of internal corporate communications, web endpoints, and API services supporting E-Zorg's healthcare operations, including patient data management and insurance services.
Notable
- Registrants for both announced prefixes are
E-Zorg B.V., which aligns directly with the AS holder. - The address inventory is compact, consisting of one /21 and one /22 block, indicating a focused corporate estate rather than a broad consumer base.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 432 networks and 1,768 prefixes, as published 2026-10-12. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
