Public Services

Services provided for use within DN42


This website is built using Hugo and is distributed across burble.dn42 core nodes.

The public internet site is a CloudFlare pages application and the source is published in the burble.dn42 git.

Service Administration Portal

The service portal allows you to configure your burble.dn42 services.

Functionality includes:

  • Setting or changing a burble.dn42 LDAP password
  • Changing your shell for the shell services
  • Viewing peering information

Diagnostic Services

Looking Glass

The burble.dn42 looking glass is based on bird-lg-go with some local customisations. The source code for the looking glass is available on the burble.dn42 git.

The looking glass is replicated via the nomad cluster, with the public version behind CloudFlare.

Pingable IP address

  • pingable.burble.dn42
  • 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.

Speed Test

The speed test service provides a way for you to measure your latency and bandwidth to the core burble.dn42 service clusters.

The service is based on is OpenSpeedTest.

The speedtest service is delivered via the internal traefik and nomad clusters which are anycasted and have internal load balancing. This means that the particular server providing the speedtest is non-deterministic and you may get different results across speedtest runs.
The speedtest service is provided for your benefit, please don’t abuse the service or using excessive bandwidth.

Network Status and Reporting

Grafana Dashboards

Uptime monitoring

Major nodes are also monitored off-network by UptimeRobot.

Anycast / Dynamic Route Monitoring

Realtime dashboard for anycast / dynamic services. Anycast status is reported every minute to the nats.io cluster and the dashboard is a live visualtion of the current status.

Internal monitoring

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.

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

Shell Accounts

The burble.dn42 shell service provides shell accounts for dn42 users who have a burble.dn42 password or SSH auth methods in the registry.
See the Shell Accounts page.

S3 Compatible Object Store

A min.io instance provides S3 compatible storage space for users that have registered a burble.dn42 password.
See the S3 Object Storage page for more information and examples.


Service Name IP
Authoritative Service ns1.burble.dn42
Recursive Service dns.burble.dn42
DNS64 Service dns64.burble.dn42 fd42:4242:2601:ac53::64

burble.dn42 provides a local, anycast, authoritative and recursive DNS service.
The DNS Service has it’s own page.

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.

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).
The OpenBGPD files can be used directly with OpenBGPD to implement ROA checks as details in the DN42 Wiki OpenBGPD
