Hosting RIPE
Summary
n@work Internet Informationssysteme
enterprise isp hosting legacy
WORK-AS is held by n@work Internet Informationssysteme GmbH, a Hamburg-based German ISP and hosting provider. It announces about 22k IPv4 addresses across 18 prefixes with 112 observed neighbours, a well-connected mid-size network.
What it's used for
The space carries a mix of business access, hosting and DSL. Reverse DNS includes server/colocation naming (pluto0.static.serverconfig.center, saturn100.static.serverconfig.center, netgate.ham1.rog.network) alongside DSL-access hosts under workdsl.de (dial50001.workdsl.de, kaibosse.workdsl.de). This is a B2B connectivity and hosting operator that also runs its own DSL access product.
Notable
- The comparatively high neighbour count (112) shows meaningful peering for a network of this size, typical of a Hamburg-region ISP with an IXP presence.

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 1,784 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.
