Unclassified RIPE
Summary
Nova Internet
isp business hosting
Twelve fragments of Spanish address space, three reverse-DNS brands, and a netname that says the country twice.
What it's used for
- Internet access and hosting. 6,656 addresses in twelve IPv4 prefixes, three observed BGP neighbours, and no IPv6 announced.
Notable
- Six blocks share one netname,
ES-NOVA-990623, registered to Nova Internet S.L. Two more areES-NOVA-20191003, twenty years later. - Two blocks belong to a different company, ARSENET Servicios en Internet S.L., under the netname
ES-ES-20120828— the country code where the organisation name should be. - Most of the inventory is scattered through
212.85.32.0to212.85.51.255in/22s,/23s and a/24, rather than announced as one range. - Three different domains answer in reverse:
212.85.33.126.inproes.com,212.85.35.126.nova.es, andppp-128.34.85.212.marblenet.es.
Interesting
- Two of those reverse names spell the address forwards and the third spells it backwards. All three are generated, and each generator was written by somebody with a different idea of which end to start from.
ES-ESis a form filled in by rote. The convention is country then organisation, and whoever typed this one put the country in both fields — a small clerical fact that has been in the registry since 2012 because nothing ever forces a netname to be re-read.- Three brands answering inside one AS, plus a second company's blocks alongside, is a provider assembled from other providers. The addresses remember every acquisition even when the marketing does not.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,771 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.
