Summary

Nova System Grup

Romania · AI-generated

business small ro

ASNOVA is operated by Nova System Grup SRL.

What it's used for

  • The space carries business traffic, indicated by the netname NOVA-SYSTEM-GRUP and the registrant ABUSE ICI LIR.
  • The AS announces 512 IPv4 addresses in a single prefix (81.181.170.0/23) with 0 IPv6 prefixes.
  • With 1 observed neighbour, the network functions as a small, isolated business endpoint rather than a transit or access provider.

Notable

  • The registrant ABUSE ICI LIR differs from the AS holder ASNOVA NOVA SYSTEM GRUP SRL, suggesting the address space was allocated via LIR (LIRNOVA) or is managed under a different administrative entity.
  • The inventory consists of a single contiguous /23 block, indicating a compact, self-contained corporate estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-05, 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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
