Summary
sinma GmbH
hosting legacy
SINMA-ASN belongs to sinma GmbH, a Berlin-based full-service internet provider for business customers, operating data-centre footprints in Berlin and Frankfurt am Main. The AS carries hosting, colocation and business-connectivity space, not consumer broadband.
What it's used for
Server hosting, server housing/colocation, VPN and fixed-line business connectivity. The announced inventory is built around 83.223.64.0/19 plus 45.145.8.0/22 and 185.219.152.0/22, and the sampled reverse DNS splits cleanly into two families:
- sinma's own infrastructure —
sinma-fra.sinma.de,melmac.ffm.mind-the.sinma.de,network-NNN.sinma.de. Themind-thelabel is a fossil of mind internetservices, the predecessor operation the founders ran from 1991 before incorporating sinma in 2001. - a large block of
hostsharing.nethosts —roNNNNNN.hostsharing.net,vmNNNN.hostsharing.net,cdsNN.hostsharing.net— the German Hostsharing eG hosting cooperative riding sinma's network.
Notable
- Server, router and VM naming throughout. There are no
dsl-,pppoe-,dyn-orpool.markers, so this is hosting space rather than an eyeball network, despite sinma also selling DSL with static IPs. - Peering is at DE-CIX and BCIX, consistent with a Berlin/Frankfurt regional provider rather than a national carrier.
- A tenant's reverse DNS dominating a provider's space is normal for small hosts. The prefixes still belong to sinma.
- The arrangement is documented in the reverse zone in plain language: one sampled address resolves to the literal string
reserviert-fuer-hs— German for "reserved for HS", i.e. set aside for Hostsharing. Reverse DNS occasionally states an operator's intentions outright.

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: 442 networks and 1,783 prefixes, as published 2026-10-20. 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.
