Internal Network Architecture


The architecture of the internal network is still to an early stage. Basically, only three networks have been defined:

Not all links are active right now.

At the moment, we decided to have 256 networks /64 allocated to the main site (i.e. a /56), and each different site has its own /56. This choice allows using the reverse DNS delegation in a simplest way, since reverse delegation has to be done on 4bit boundaries.

Therefore, the present allocation looks like:
