Does anyone have any suggestions, or example code, on how to handle allocation of sub blocks from a CIDR allocation. Previously Connect has allocated a /24 as the minimal block but now the APNIC have advised that they do not consider this allocation policy to be efficent as defined by RFC 2050 and so I am trying to recode our procedures.

I would like to find (or else write) some code that will "optimally" allocate sub blocks and generally manage our allocation (so I can return blocks to the pool when customers leave etc). For routing convenience (optimisation) I would like to also collect together sub /24 allocations for specific POPs so that we don't need to announce all the sub /24 blocks to multihomed customers, peers and providers.

Any ideas? Or pointers to other people to ask (the APNIC have been silent on the issue after requiring us to do it before they will issue us another block).

Mark.

Have you looked at TREE? There ought to be a valid pointer from teh NAP page. -- --bill
