About this network

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::/29 and 2a0e:8c00::/29.
• Dated netnames run DE-IAV-20171013, DE-IAV-20190409 and DE-IAV-20190805.
• Two older blocks carry bare netnames, IAVGB and IAVGB2.
• One sampled address answered, as na.nettransinet.5g-campus.iavtech.net.
• First observed in the routing archive in January 2010.

Interesting

• 5g-campus is 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.
