hosting business enterprise research
The same netname prefix carries dates on some blocks and addresses on others.
What it's used for
- An information technology services provider. Nine IPv4 prefixes and two IPv6 prefixes announced from Germany, eleven thousand addresses, across sixteen observed BGP neighbours.
Notable
- Four blocks share a netname prefix built from the country code and the company name. Two of them end in an allocation date; two end in the block's own address digits run together with no separators.
- Two blocks belong to a research society and carry a netname containing the word intranet, applied to space that is announced to the public internet.
- Two more use registry organisation identifiers as their netname, which is a database key rather than a name.
- One block's registry lookup failed, so nothing can be said about who holds it.
- Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- One prefix scheme with two different suffix rules is what happens when a convention outlives the person who invented it. Later entries follow the shape without knowing the rule.
- Calling a routed block an intranet is a label from the inside. It says how the operator thinks of the space, not how the internet reaches it.
- Sixteen neighbours for eleven thousand addresses is a well connected provider that hosts other organisations' networks alongside its own.

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 1,773 prefixes, as published 2026-10-13. 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.
