Summary

hosting isp transit
301 IPv4 announcements for 150,016 addresses, four separate IPv6 allocations, and a placeholder published in public DNS.
What it's used for
- Hosting and connectivity in Germany. 150,016 addresses in 301 IPv4 prefixes, 38 IPv6 prefixes, and 59 observed BGP neighbours.
Notable
- The blocks are split fine: 301 announcements average under 500 addresses each, and the listed prefixes are mostly
/22s out of5.230.0.0and5.175.0.0. - Netnames run
DE-GHOSTNET-20080918,DE-GHOSTNET-20120802andDE-GHOSTNET-20120911. - One block in the middle of the inventory is
DE-Ackermann-IT, registered to a named individual, Sascha Ackermann. - Four of the IPv6 announcements are separate
/29s:2a00:12d8::/29,2a00:19d0::/29,2a01:bd40::/29and2a02:7a0::/29. - One sampled address answers
placeholder.noez.de. - First seen in routing data in June 2002, a real date rather than the floor of the archive.
Interesting
- A
/29is a full registry allocation to a member, and holding four of them means being four members, or having absorbed three others. IPv6 blocks are the clearest fossil record of corporate acquisition available, because nobody bothers to consolidate address space that costs nothing to keep. placeholder.noez.deis exactly what it says: a name filled in so the field would not be empty, published to the world and still answering. Reverse DNS is the one part of a network where temporary decisions become permanent in public.- Five further announcements subdivide a single
/44into pieces of four different sizes, which is the shape of address space handed out to customers one request at a time.

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: 431 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.
