DN42 Build out

Reading time ~1 minute

While using just a few nodes for DN42 has been I thought for fun I would deploy a few more POP’s around the world (The HE IPv6 video on sparse allocation might have helped!).

As such I introduce a number of new changes. I’ve extended my dn42.cycloptivity.net sub domain to include a country code for each node.

  • au01.dn42.cycloptivity.net - Aspley, Queensland

    My residential crappy ADSL2+ tail with routing via Ubiquiti EdgeRouter Lite. Currently blazes at 6/0.8Mbps. Eventually will move to a FTTH 100/40 service and host AU services for DN42. In the meantime au01.dn42.cycloptivity.net will no longer provide transit. Future nodes may include a Cisco 877 and Juniper SRX110 once bandwidth improves.

Currently the last remaining POP to go live will be jp01. All other nodes are already alive and able to provide transit (albeit sub-optimal in some cases). At this time all nodes are providing IPv4 only. Native IPv6 is planned next.

I’ve created a brief diagram showing average RTT between each node.


I am starting to make use of the phpipam tool to track address usage.

CYCLOPTIVITY-DN42 ( has 4 directly nested subnets:

Subnet description	    Subnet	            Used	% Free	
au02.cycloptivity.dn42	    11/30   63.33		
jp01.cycloptivity.dn42	0/30	100		
us01.cycloptivity.dn42	2/30	93.33		
de01.cycloptivity.dn42	1/30	96.67	

Hopefully, I can make use of the phpipam API to create a automatic rdns tool. Tracking all the various interfaces is getting fairly tedious!

Thats all for now! If your interested in this sort of shenanigans please visit dn42.net!
