AS14398 — AUTODESK

AS14398 announces 10 IPv4 prefixes covering 79,104 addresses and 0 IPv6 prefixes.

About this network

More than half the address space belongs to a subsidiary on the other side of the world, registered through a different registry.

What it's used for

• A software company's corporate network. 79,104 addresses across 15 IPv4 prefixes, with six observed BGP neighbours and no IPv6 announced.

Notable

• 147.176.0.0/16 carries the netname AUTODESKLTDJAPAN-JP and an incident-response object named IRT-AUTODESKLTDJAPAN-JP.
• The remaining thirteen 132.188 prefixes all carry the netname AUTODESK, registered to Autodesk, Inc. with a hostmaster contact.
• Those thirteen run from /20 down to two adjacent /24s, 132.188.70.0/24 and 132.188.71.0/24.
• 203.202.234.0/24 is the fifteenth prefix.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• One block holds most of the 79,104 addresses, and it is the subsidiary's rather than the parent's. Regional offices that registered early sometimes hold more space than the head office ever needed, because the head office started asking later, when the answers had got smaller.
• The 132.188 range is announced as thirteen pieces down to a pair of adjacent /24s. Splitting two consecutive blocks rather than announcing one /23 is a routing decision, not an allocation one: the two halves go somewhere different.
• An incident-response object exists on the subsidiary's block and not on the parent's. The registry that issued it requires one; the registry that issued the rest does not.
