Unclassified RIPE
Summary
IAV
enterprise research business
An automotive engineering firm with two IPv6 /29s, 107 neighbours, and a private 5G network named in its reverse DNS.
What it's used for
- Networking for an automotive engineering consultancy. 3,584 addresses in five IPv4 prefixes, two IPv6 prefixes, and 107 observed BGP neighbours.
Notable
- Both IPv6 announcements are
/29s:2a0d:d400::/29and2a0e:8c00::/29. - Dated netnames run
DE-IAV-20171013,DE-IAV-20190409andDE-IAV-20190805. - Two older blocks carry bare netnames,
IAVGBandIAVGB2. - One sampled address answered, as
na.nettransinet.5g-campus.iavtech.net. - First observed in the routing archive in January 2010.
Interesting
5g-campusis a private cellular network run on a company's own premises, using licensed spectrum set aside for industrial use. An engineering firm that tests vehicles needs radio coverage it controls, and naming the block in reverse DNS tells anyone looking that the addresses behind it belong to test equipment rather than to offices.- Two
/29s is sixteen times the standard IPv6 allocation, and 107 neighbours is a service provider's peering count rather than a consultancy's. Together they suggest a company whose network carries more than its own staff, which is what happens when engineering services are delivered to customers over dedicated connections. - Three IPv4 allocations in under two years, all
/22s, is the modern pattern: small blocks, bought or assigned as needed, from unrelated ranges. The two undated blocks predate that era and cannot be aggregated with anything.

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 1,772 prefixes, as published 2026-10-15. 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.
