Unclassified RIPE
Summary
Unisystems
business enterprise hosting
Two blocks share one netname, but only one of them lists the company that name refers to.
What it's used for
- An information systems company's network. Two IPv4 prefixes announced from Greece, no IPv6, seven hundred and sixty-eight addresses, across two observed BGP neighbours.
Notable
- Both blocks carry the same netname, the company's brand in mixed case where most netnames are capitals.
- On the first block the registrants are the company under its legal form and an abuse role. On the second they are two roles belonging to an internet provider, one administrative and one technical, with the company itself absent.
- So the same label means two different things depending on which block you look at: on one it names the holder, on the other it names a customer of the registrant.
- The AS handle runs the brand together with three more capitals and no separator anywhere.
- Six addresses were queried for reverse DNS and none returned a name.
Interesting
- A provider registering a customer's block under the customer's own name is the polite version of the arrangement, and it produces exactly this: the name is right, the contacts belong to somebody else, and nothing in the record says which is which.
- Systems integrators are the least visible large businesses on the internet. The work happens inside other organisations' networks, so their own address footprint stays small no matter how big the company gets.

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.
