> Subject: Hosting Address space Issues
>
>
>
>
>
> I am sending this email to explain the impact to our Hosting IP
> Address space due to the recent audit by ARIN. The impact is greater
> than we expected ARIN has reviewed all the IP Addresses assigned to
> Savvis Hosting (Legacy Exodus/ DI ) and have requested that we return
> all IP Addresses that are not in use or the 0% usage, and also they
> requested all the IP Addresses that are in the 1% usage range.
>
> We are required to have 80% utilization of any assigned block of IP's
> at any given time, or when we request additional space or when we do
> any kind of transfer. In this case it was due to the transfer to
> Savvis and the Separation from Cable & Wireless PLC.
>
> We have returned the following IP Blocks to ARIN as of Aug 5th, we
> have also transferred three blocks to Cable & Wireless. We have a few
> customers who have not renumbered out of some additional space that we
> have to return to ARIN, and they have been contacted and provided
> replacement IP's
>
>
> The issues I see for our Hosting customers are
> 1.) a reduced amount of IP Space at each hosting center
> 2.) and increased chance that a customer might be assigned a block
> from a previous customer who might have gotten the assigned block on a
> black list or spam list.
>
> 3.) a reduced amount of diverse IP Space for customers who request it.
> 4.) we will not be in a position to replace IP's for customer once
> they appear on one of the spam or black lists
> 5.) and increased amount of black listed or spam listed IP Space
>
> The long term of this will be the lack of clean ip's to assign to
> customers.
>

> The following blocks may be reclaimed by ARIN as per your request:
> 64.15.0.0/20
