AS13481 — AMS-AGD-PR

AS13481 announces 2 IPv4 prefixes covering 1,280 addresses and 0 IPv6 prefixes.

About this network

Two blocks out of a legacy /8, announced through a single upstream, first seen in routing only recently.

What it's used for

• A technology company's network. 1,280 addresses across two IPv4 prefixes, one observed BGP neighbour, and no IPv6 announced.

Notable

• Both 16.7.28.0/22 and 16.1.3.0/24 are netname HPE-15, registered to the company.
• Both addresses start with 16, from a whole /8 held by the company since the early allocations.
• The AS handle is AMS-AGD-PR, matching neither the company name nor the netname.
• First seen in the routing archive on 2023-02-11, an actual date rather than the archive's start.

Interesting

• Announcing 1,280 addresses out of a /8 is the shape of a very large holder carving off a piece for one purpose. The rest of that /8 is announced elsewhere, or not at all, and this autonomous system sees only the sliver it was given.
• A first appearance in routing decades after the number was issued means it sat unused. Large companies hold pools of numbers and turn them on when a project needs its own routing identity.
• The handle is a project or site code from inside the company: initials that meant something to whoever filled in the form, and nothing to anyone reading the record afterwards.
