>Hi All,

>This is with respect to Part 1 of the feature 'Dedicate Public IP range' which is
>already implemented in CS.
>Following is the observation wrt what is the current CS implementation and the
>proposed changes to the same,
>
>1.       A public VLAN-IP range can only be associated to an account during the
>creation of the range
>Proposed change - Admin should be allowed to dedicate a range even after it
>has been created and also allowed to change the owner
>
>2.       If an admin associates an IP range to an account, all the IP's of that range
>get acquired by a single isolated network in that account
>
>a.       If there are no isolated guest networks, a new network is created and all
>the IP's from the range are dedicated to the new network
>
>b.      If there is 1 isolated guest network, all the IP's from the range are
>dedicated to the existing network
>
>c.       If there are more than 1 isolated guest network CS throws an error
>
>               Proposed change - When an account is chosen, the user also has the
>option to choose the network in the account which can acquire the IP's
>
>3.       When a network that has a dedicated IP range is deleted, the mapping
>between the account that owned the network and IP range persists. This implies
>that the admin sees that the range is associated to the account. But the IP's from
>this range can be acquired by any other account
>
>Proposed change  - The IP range should no longer be owned by the account
>
>4.       When an account is deleted the IP ranges dedicated to that account get
>deleted
>
>Proposed change - The range should be released back to the free pool instead
>
>5.       I see a potential starving scenario where a certain account that has
>dedicated range uses up all the IP's from the free pool as well
>
>Proposed change  - Impose a configurable limit like say, at least one range
>should always belong to the free pool
>
>6.       Even if a range is dedicated to an account, any network that belongs to
>this account including the one that has acquired the IP's can acquire more IP's
>from the free pool. This is because when we dedicate an IP range to an account,
>one of the networks of that account acquires all the IP's.
>
>Proposed change - During dedication we just mark this range of IP's as
>dedicated. And only when the user acquires an IP for a particular network we
>allow the network to choose from the dedicated range. If this change is
>implemented we will not run into issue #2.
>
>Please provide your feedback. I will publish an FS keeping in line with the
>requirements we decide upon.
