Unclassified RIPE
Summary
Audi AG
enterprise legacy
The corporate network of Audi, the German car manufacturer.
What it's used for
- Corporate networking. 65,536 addresses, all of it a single legacy class B registered as
NET-AUDIto the company's own RIPE administrators.
Notable
- The
/16is announced as five pieces rather than one: a/17, a/18, a/19and two/20s, which add up to exactly the whole range and nothing more. - Three observed BGP neighbours. A network holding 65,536 addresses and reaching the rest of the internet through three peers is an end site, not a carrier.
- One IPv6 prefix, a
2001:678:35c::/48, from the range RIPE reserves for provider-independent assignments — space that belongs to the holder rather than to whichever network happens to be announcing it.
Interesting
- Splitting a
/16into five announcements that reassemble into the original is usually about steering: each piece can be given a different path, so traffic for one part of the company arrives over a different link from another. The alternative, announcing the/16whole, gives the operator no control over which of its three upstreams inbound traffic chooses. - A manufacturer of this size runs plants, engineering and dealer systems on one address block, and the assembly line is the part with no tolerance for an outage: modern car production is scheduled to the minute, and stopping the line is measured in cars per hour not built.

Peering at a glance
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 2026-10-15, 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 1,781 prefixes, as published 2026-10-16. 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.
