isp hosting business
Seventy-five BGP neighbours on two blocks, and not one reverse name.
What it's used for
- A German internet and systems provider. 12,288 addresses across two IPv4 prefixes, 75 observed BGP neighbours, and no IPv6 announced.
Notable
- The inventory is
85.112.224.0/19and81.201.224.0/20. - The netnames are
DE-WIZARD-20050201andDE-WIZARD-20021017, three years apart. - Both blocks end at
.224.0, though they sit in different ranges. - Six addresses were sampled and none returned a name.
Interesting
- Seventy-five neighbours is a peering profile, not a customer profile. A provider with 12,288 addresses and that many BGP relationships is spending its effort on exchanging traffic directly with other networks rather than on holding address space, which is what a regional provider does when transit is the expensive part of the bill.
- Two allocations three years apart, both landing at
.224.0in their respective ranges, is coincidence rather than design. The registry assigns from whatever is free, and patterns that look intentional in address data usually are not. - Nothing answers reverse lookups. For a provider this is a real gap: mail servers on space with no reverse names get treated with suspicion by receivers, and traceroutes through the network show bare addresses. Whether that matters depends entirely on what the space is used for, and the absence itself is a small piece of evidence that it is not general hosting.
- No IPv6 at all from a network that peers with seventy-five others, most of which will have it.

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: 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.
