[INSTRM-163] Allocation of CIDRs for subsystems on the real network

Blocks — Wed, 21 Feb 2018 17:51:14 +0000

Not linking to ~~INSTRM-70~~, since this is a task for real allocation of resource.
We need to have definition and/or registration of allocation of subnets for subsystems at somewhere, as well as DHCP definitions in dnsmasq. So, we need to agree in this ticket on:

where (repository) and how (description file format) we will register allocations
registration management - will not change so much (it's subnet but not address)?
basic idea of allocation

Requirements (or desires?) of allocation criteria should be:

pack related subsystem in close subnet (e.g. xCU follows ENU), and in organized order (e.g. SM2 follows SM1)
allocate by one CIDR (to make thing simple) as much as possible, with slack in each subsystem
first address (.164.1) will be taken by default gateway (port at Subaru core switch), so we'd better to assign first CIDR to network switch subsystem
