TO ALL COLO/DEDICATED ACCESS CUSTOMERS:

Several months ago, Netsville received IP space directly from ARIN
(American Registry for Internet Numbers).  This process took roughly 
a year to complete as there were a number of requirements we had to 
meet.  We went through this process for a number of reasons:

  * more flexibility in choosing upstream providers
  * larger address space for us and our customers
  * direct control over routing and reverse IP assignment

ARIN requires that we give back all our previous address space owned
by upstream providers.  This means we must switch all our customers
over to these new IPs.

We have been slowly notifying and migrating customers over to these
new blocks of addresses, however, recent events have forced us to 
speed up this procedure.

NTT/Verio, one of our upstream providers, has suddenly and without
warning removed our nameservers from their servers that control
"reverse IP resolution".  In a nutshell, this means we can no longer
resolve IP addresses that they own.  This stems from a recent
dispute that is unrelated to the new addresses.  Why they've chosen
this unreasonable path after 6 years of doing business with them
is beyond me.

The immediate result some customers are experiencing is bounced email
because of this lack of reverse resolution.  We will shortly be
contacting everyone, many for a second time about switching IP
addresses.

We understand all too well the inconvenience this causes and it is our
intention to guide you in any way we can to minimize any downtime.

The important thing to note is after this change, the addresses we
assign will be owned by Netsville.
