Summary

synaforce GmbH

Germany · AI-generated

hosting datacenter business

HARTL-EDV-AS is operated by synaforce GmbH.

What it's used for

  • The address space carries infrastructure for data centers and enterprise services, evidenced by netnames such as DE-HARTL-GROUP-20190410, DE-ROHWERDER-20160613, and DE-ISC-CONSULTING-20180413.
  • The AS announces 8,960 IPv4 addresses across 12 prefixes and 13 IPv6 prefixes, with 5 observed neighbours, indicating a hosting or data center provider role rather than a large-scale residential access network.
  • Traffic from this AS consists of web/API endpoints, data center workloads, and enterprise backhaul for clients like Rohwerder Datasystems and DATAGROUP Enterprise Consulting.

Notable

  • Registrants include NOC Hartl Group, synaforce GmbH, Rohwerder Datasystems GmbH, DATAGROUP Enterprise Consulting GmbH, Autphone GmbH, and ITecon GmbH, reflecting a portfolio of acquired or managed IP blocks.
  • The Hartl Group rebranded as synaforce following investment by Afinum, with subsequent acquisitions including Abakus and Trikom GmbH.
  • The inventory is a mix of /22 and /24 blocks, with some prefixes registered under legacy Hartl Group names and others under specific client or subsidiary entities.

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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
