Summary

Intesa Sanpaolo

Italy · AI-generated

finance enterprise business

The handle ISP-ASN4 belongs to a bank, and the n4 is a serial number.

What it's used for

  • A network of an Italian banking group. 3,584 addresses across four IPv4 prefixes, one IPv6 prefix 2a00:b740:5::/48, and two observed BGP neighbours.

Notable

  • The registry holder is recorded as ISP-ASn4 with a lowercase n; the AS handle is ISP-ASN4.
  • Netnames are ISP-NET-n3, ISP-NET-n4, ISP-NET-n5 and IT-INTESASANPAOLO.
  • Every block lists the role object Admin TLC as a registrant; only two also name the bank.
  • Two observed neighbours against 3,584 addresses.

Interesting

  • ISP reads as the standard abbreviation for an access provider, and here it is the bank's own initials. This is the second network in this range where those three letters mean a financial institution rather than a service provider, which makes the abbreviation useless as a filter.
  • The n3, n4 and n5 series says this AS is one member of a numbered set, and the same number appears in both the AS handle and the netnames. The bank runs several autonomous systems and labelled them the way an accountant would.
  • The lowercase n in the holder field and the uppercase N in the handle are the same identifier entered twice by different hands. Nothing resolves the difference because nothing has to.
  • Two neighbours is the profile of a network that buys connectivity and sells none.

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 1,783 prefixes, as published 2026-10-20. 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.
