The burble.dn42 looking glass is based on bird-lg with patches by Zhaofeng, tds and myself to fix formating, bird2 compatibility and other tweaks.

A fork of sileht/bird-lg that includes all of our fixes is available on GitHub.

Please note that updates to the wiki may take several hours to sync with other mirrors.

The service is provided by regional mirrors fronted by an nginx proxy that is itself anycasted across burble.dn42. The service is fully meshed and will continue to operate as long as at least one proxy and mirror is available. The maximum latency across the network is <80ms.
Mirrors are located in the following locations:

  • dn42-fr-sbg1
  • dn42-ca-bhs2
  • dn42-us-dal1
  • dn42-sg-sin1

Pingable IP address

  • pingable.burble.dn42
  • 172.20.129.5
  • fd42:4242:2601:ac05::1

pingable.burble.dn42 is a single IP address that will respond to ping and traceroute requests across the entire network.

This address may be used for automated reachability or latency tests, however please be considerate and configure a reasonable test frequency. In all cases, do not set the ping frequency to be higher than once a second.

Registry API Service and Explorer

dn42regsrv is a REST API for the DN42 registry that provides a bridge between interactive applications and the registry.

As well as the main REST API to the DN42 registry, the server can also generate ROA tables and provides a small web application for exploring registry data.

A public instance of the API and associated explorer web app is available at the following URLs:

Whois Service

  • whois.burble.dn42
  • fd42:4242:2601:ac43::1
  • 172.20.129.8

WHOIS service providing data from the DN42 registry.

The source code for the service is available in the burble.dn42 git.

Global Route Collector

The global route collector provides a central bird instance that collects routes from peers across the DN42 network.
All users are invited to join the collector and help provide stats for the network.

The route collector can currently be queried by using ssh to connect a bird shell or via a looking glass.
Additional services and stats are expected to be developed in the future.

ROA Data

Route Origin Authorisation (ROA) tables are generated using dn42regsrv and published to the dn42.burble.com website for general use.

The JSON output file can be used with gortr to implement ROA checks via RPKI.
The Bird files can be used directly with Bird to implement ROA checks as detailed in the DN42 Wiki (Bird1 / Bird2).

DN42 Infrastructure Monitoring

burble.dn42 hosts monitoring and alerting of key DN42 services, see the hosted grafana service for more details.

burble.dn42 status

dn42.status.burble.com

Each node in the network is monitored by UptimeRobot with alerts if a node becomes unavailable.

Internally, nodes are measured by netdata which provides a real time view of each node. prometheus is then used to collect and store that data for historical reporting. grafana is used for visualisation. Some public graphs are available on the hosted grafana service.

Syslogs are exported in real time to a central logging node on the internal network.
