Summary
Elbracht-Computer Netzwerk & Grafik Service GmbH
business germany small
The AS handle ELBRACHT-COMPUTER-AS is held by Elbracht-Computer Netzwerk & Grafik Service GmbH.
What it's used for
- The address space carries internal corporate infrastructure, evidenced by the reverse DNS record
cus254-als.elbracht.netpointing to the company's own domain. - The network announces a single IPv4 prefix, 217.73.144.0/21, comprising 2048 addresses, against 16 observed neighbours. This ratio of a small, single-block inventory to a moderate number of peers suggests a small business or enterprise network rather than a large transit or access provider.
Notable
- The RDAP registrant for the announced prefix is listed as
unknownwith the netnameRIPE-NCC-MANAGED-ADDRESS-BLOCK, which does not explicitly match the AS holder name in the registry, though the reverse DNS confirms the space is used by Elbracht. - The address inventory consists of a single contiguous /21 block with no IPv6 prefixes announced, indicating a focused IPv4-only deployment.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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.
