hosting isp business
Three sampled addresses all answer with the single word unassigned.
What it's used for
- A hosting provider. Two IPv4 prefixes and one IPv6 block announced from Germany, four thousand three hundred and fifty-two addresses, through one observed BGP neighbour.
Notable
- Three of six queried addresses answered, and every answer is the same bare word declaring the address unassigned, with no domain attached to it at all.
- A hostname with no dots in it is unusual enough to be worth stating plainly: the zone is returning a label rather than a fully qualified name.
- The company's own name is a domain name, the word for a dot followed by the national suffix, so the brand is a joke about the notation it is written in.
- One netname is a country code, an unrelated brand and a date from the year two thousand. The other names a systems planning company and is registered to that company, not to the holder.
- The first block lists the holder and its own hostmaster role; the second lists only an abuse role.
Interesting
- Three different placeholder words for unused space turn up across this range, and this is the tersest. Each of them tells a scanner the same thing: something answered, but nothing is meant to be there.
- A provider that announces a customer's block under the customer's own registration is doing the normal thing. The AS number is the provider's, the addresses are not, and only the record shows the seam.

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.
