Summary

Grandi Navi Veloci

Italy · AI-generated

shipping ferry corporate italy

ASGNV is held by Grandi Navi Veloci S.p.A., an Italian ferry operator based in Genoa.

What it's used for

  • The address space carries corporate infrastructure for the ferry company, as indicated by netnames IT-GNV-20160506 and GNV-NET registered to the company.
  • The AS announces 1280 IPv4 addresses across 2 prefixes with only 2 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate systems, office workers, and operational endpoints supporting GNV's passenger and freight maritime transport services.

Notable

  • Registrants for both announced prefixes match the announcer, with Grandi Navi Veloci S.p.A and GRANDI NAVI VELOCI SPA listed in RDAP records.
  • The address inventory is compact, consisting of one /22 and one /24 block, consistent with a single corporate entity managing its own IP space for internal use.

Reputation

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
