Autonomous system
AS15887 INFOGROUP-AS
Unclassified RIPE
Summary
Engineering Ingegneria Informatica
business enterprise hosting
The handle names a group brand that appears nowhere in the company name or the netname.
What it's used for
- A systems integrator's network. One IPv4
/21announced from Italy, no IPv6, two thousand and forty-eight addresses, through a single observed BGP neighbour.
Notable
- The AS handle is a contraction of the word for information with the word for a group, plus the two letters for an autonomous system. The holder's registered name uses neither word.
- The netname is a country code, the first word of the company name, and the date
20091104. - The first registrant is not the company but an administrative role for the organisation that holds the registry membership, written as two abbreviations and a title.
- The third contact is the company name again, hyphenated end to end and followed by the word for a role.
- Two thousand addresses, one route, one upstream.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- A registry membership can be held by one entity on behalf of several, which is why the first contact on a block is sometimes an administrator rather than the user. The group brand in the handle and the membership role in the registrant are two views of the same arrangement.
- One route and one upstream on two thousand addresses is a company network that outgrew provider space, not a service network. Nothing here is being sold onward.

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 2026-10-19, 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 1,783 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.
