Internal services

You are asked to show some creativity in terms of network usage and content. ;)

More inspiration is collected here and here.

Search engine

There is a search engine at search.dn42 that can also be used to discover services and content. It attempts to index all sites on DN42.

Certificate Authority

xuu is maintaining an certificate authority for internal services.

n0emis maintains an ACME server (with accompanying CA), compatible with any LetsEncrypt client like Certbot, Dehydrated or Caddy.


GeoIP Services

Map.dn42 provides a simple GeoIP service. This service uses rDNS records and country field in aut-num objects as a reference, currently designed for fun :P


Results are in JSON format.[DN42_IP]&lang=en[DN42_ASN]


There is a client software using above apis to provide GeoIP-based traceroute. It is a modified IPIP.NET Best Trace software with DN42 support injection.

Windows only, no virus scan report available, but our DLL source is provided with the modified client. It's highly recommended to run this tool in a sandbox.

** Since the original software is not open source, so use it at your own risk. **

ASN Authentication Solution

Authenticate your users by having them verify their ASN ownership with KIOUBIT-MNT using their registry-provided methods in an automated way. An example of this is the automatic peering system for the Kioubit Network. To use the service, please message Kioubit on IRC to have your domain activated and receive the required documentation.
