AS13527 — GOOFL-TESTBED

AS13527 announces 1 IPv4 prefixes covering 512 addresses and 8 IPv6 prefixes.

About this network

The handle says testbed, and there are fourteen IPv6 prefixes against a single IPv4 block.

What it's used for

• A network described in its own handle as a testbed. 512 addresses in one IPv4 prefix, 199.188.148.0/23, fourteen IPv6 prefixes, and two observed BGP neighbours.

Notable

• The AS handle is GOOFL-TESTBED.
• The IPv4 block is netname SAL-309, registered to a company with a different name from the holder.
• Every IPv6 prefix begins 2602:f83d:, split into sizes from a /43 down to a /48.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• Announcing one range as fourteen separate prefixes of six different sizes, through two upstreams, is what a testbed looks like from outside. Nobody needs that many routes; somebody is exercising how announcements propagate, which sizes get filtered, and how the table reacts.
• Fourteen IPv6 prefixes against one IPv4 block inverts the usual ratio and fits the same reading. A network experimenting with routing does it where address space is cheap.
• Saying TESTBED in the handle is a courtesy to everyone watching the routing table. Anomalous announcements from an unlabelled network get investigated; from a labelled one they get ignored, which is what both sides want.
