AS14085 — LEARN-I2PX

AS14085 announces 2 IPv4 prefixes covering 512 addresses and 2 IPv6 prefixes.

About this network

A research and education network, with the exchange it connects through named in the handle.

What it's used for

• A regional research and education network. 512 IPv4 addresses across two prefixes, two IPv6 prefixes, and four observed BGP neighbours.

Notable

• Both 74.200.183.0/24 and 74.200.190.0/24 carry the netname LEARN, with an operations role named after the organisation in each registrant field.
• The IPv6 announcements are 2607:f928:5::/48 and 2607:f928:15::/48, from the same larger block.
• The AS handle appends a suffix naming a research network peering exchange.
• Six addresses were queried for reverse DNS and none returned a name.

Interesting

• Regional research networks exist to connect universities to each other and to the national research backbones, at capacities and costs no single institution could arrange alone. The handle records which exchange this one uses to reach the rest of that world.
• Naming an operations centre rather than a person in the registrant field is the practice these networks have followed the longest, and it is the practice the commercial records in this range keep failing to adopt.
• Two IPv6 blocks from one range, announced separately rather than as one covering block, is a small inefficiency and a common one.
• Four neighbours over a small footprint is what a network built for interconnection looks like: the value is in the paths, not the addresses.
