Unclassified RIPE
Summary
Materna
business enterprise hosting
Six fragments of an old large block, adding up with one newer prefix to exactly four thousand addresses.
What it's used for
- An information technology services company. Seven IPv4 prefixes announced from Germany, no IPv6, four thousand addresses, through two observed BGP neighbours.
Notable
- Six of the seven blocks are small pieces cut from one older range, two
/23prefixes and four/24prefixes scattered through it with gaps between them. - The seventh is a
/21from elsewhere and holds half the company's total address space on its own. - The
/21carries its own netname; the six fragments all share a different one, so the two holdings were recorded in separate eras of registry practice. - Every block lists the company and an abuse role, with no variation across the seven.
- Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- The seven pieces total exactly four thousand and ninety-six addresses, which is a coincidence of arithmetic rather than planning: two halves of a
/21worth of fragments plus a whole/21. - Announcing four separate
/24prefixes out of one range costs four routing table entries worldwide for a thousand addresses. The gaps between them are the reason, and the gaps belong to somebody else. - No IPv6 at all from a company that sells communications services is the gap most worth naming here.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
