Iris Network

That is AS4242421023 on dn42.

This article is about the Iris Network, yet another experimental network, operated by Iris, that runs on dn42.

Network

Nodes

As of 2026-05-19, Iris Network has 7 nodes in 4 countries, with 3 nodes in the United States, and 1 node in each of Hong Kong, Japan, the Netherlands and France.

Topology

Iris Network has a simple topology, with all nodes forming a full mesh with WireGuard tunnels when possible1 , i.e., when a pair of nodes share a common IP version. Babel is used as the interior routing protocol.

A diagram of the topology is shown below.

BGP

Iris Network exists for BGP experimentation. The BIRD Internet Routing Daemon is deployed on all nodes to provide BGP (as well as Babel) services.

Iris Network actively peers with other dn42 participants. As of the time of writing, there are more than 200 active peering sessions with 53 unique ASNs. Previously, peering sessions were established manually, but now the autopeer portal has been doing a large portion of the work.

Infrastructure as Code

Iris Network manages its nodes and peering sessions with Ansible. Playbooks cover system configuration, WireGuard tunnel setup, BIRD configuration, DNS, the looking glass, the automatic peering system, websites and monitoring.

Looking Glass

A custom looking glass is deployed across the network.

The looking glass is accessible at network.owo.li, or network.iris.dn42 if the reader prefers dn42 access.

Autopeering

Iris Network has been offering self service autopeering through a portal at autopeer.owo.li and autopeer.iris.dn42 since April the 18th, 2026.

A public Grafana dashboard at metrics.intranet.services provides aggregate views of the network's health and performance over time.

Miscellaneous

• Iris Network is a part of the XJBCast Project, announcing 172.23.41.80/28 and fd32:3940:2738::/48 for the project.
• fra-01, while not being a node of Iris Network, does have its presence in dn42.

Open Source

The infrastructure, looking glass and autopeering portal of Iris Network are open source, and available at the following repositories:

• OwO-Intranet-Services/dn42-network contains the Ansible playbooks, GitHub Action workflows for autopeering, and up-to-date network configuration.
• el-ev/bird-lg-rs contains the source code of the looking glass and autopeering site.
