<p class="MsoNormal"><span style="color:#1F497D">I think we may intertwining two separate needs.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">The first and most urgent need is to understand how we will declare the static IP assignments for each baremetal host up front, much like we do within Airship 1.0. I disagree that MaaS behaves as an IPAM service
– for the most part all it does is enforce the static assignments we declare within Drydock BaremetalNode documents as in here:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><a href="https://github.com/airshipit/treasuremap/blob/master/site/seaworthy/baremetal/nodes.yaml#L48-L86">https://github.com/airshipit/treasuremap/blob/master/site/seaworthy/baremetal/nodes.yaml#L48-L86</a><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I missed the latest bootstrap-sig call, however when we were initially discussing this one very simple way to get
<i>started</i> with this is to represent the network configuration <i>as </i>cloud-init data in the BareMetalHost (BMH) CRD. There is support for that now without introducing any additional CRDs or fields.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">The second need you are addressing, where files/CRs like “common-addresses” become more important and have definitions for all the various subnets--abstracted from specific machines, is supporting a more liberal
IP assignment mechanism in Airship 2.0, where users need only define subnets, and we can support allocating addresses automatically. This is where IPAM truly becomes a requirement but I think it is premature to look at this and feel this may be a subsequent
step to delivering static functionality.<o:p></o:p></span></p>

the same mechanism of ip allocation for ephemeral cluster and for target cluster.<o:p></o:p></p>
