Summary

Netzhaus AG

Germany · AI-generated

housing residential germany access

POTSDAM-AS is operated by Netzhaus AG.

What it's used for

  • The address space carries residential and housing services, evidenced by the netname NH-HOUSING on the 80.86.2.0/23 prefix and the registrant identity netzhaus aktiengesellschaft.
  • The AS announces 3,840 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, while maintaining 14 observed neighbours; this ratio of moderate address space to a significant number of peering partners indicates an access network providing connectivity to end-users rather than a transit provider.

Notable

  • All RDAP registrants for the announced IPv4 prefixes are consistent with the announcer, listing Netzhaus AG Hostmaster and netzhaus aktiengesellschaft.
  • The address inventory is contiguous within the 80.86.0.0/22 range, subdivided into four distinct prefixes that collectively cover the /22 block.
  • The operator is identified in secondary sources as a content and housing provider based in Germany.

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 1,772 prefixes, as published 2026-10-15. 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.
