We have a customer who is in the process of moving from
MCI^H^H^HCable and Wireless to us. They have been using MCI/CW for a while,
and need time to renumber their equipment, have their customers change
places they have hardcoded IP addresses, etc. A quick read through RFC 2050
(IP Allocation Guidelines) talks about this situation in section 2.1:
The ISP
should allow sufficient time for the renumbering process to be
completed before the IP addresses are reused.
However, the rep they spoke with at MCI/CW seems to feel that the moment the
connection is cancelled, the IP addresses may be reassigned to another
customer, and they should not expect a grace period for renumbering.
Anybody had any experience with this before? Is it reasonable of me to
expect MCI/CW to be nice about the whole thing, and give their customer 6
months to renumber? Or is this what everybody does, taking the "should"s in
the RFC very literally?
Anybody had any luck with the appeals process on things like this?
Thanks for any experience/info/ideas/reality checks,
--------Scott.
That portion of RFC 2050, I believe, refers to renumbering within the same
ISP, where it's reasonably easy to allow time for customers to renumber.
When a customer is moving from another ISP to you, they're pretty much SOL
when it comes to their old IPs.
Hmm...
About four weeks ago, before the InternetMCI->C&W sale was finalized, the
policy was that MCI customers would have up to six months (as per RFC 2050
and generally accepted good practices) at such time the network space would
be returned to MCI's pool. A very detailed policy paper on this was posted at:
http://infopage.mci.net/Address/nonportable.html
-now-
http://infopage.cw.net/Address/nonportable.html
However, since the logo has changed, they have now removed ALL information
regarding any grace period. Maybe someone from C&W can address this? Was
this a mistake/oversight or has the policy actually changed? ...and while
your're at it, can you change the incorrect billing name on our account?
I'v been trying to get it done for 3+ years!

Our most recent renumber involved paying for an extra three months of
NetCom connectivity, until all our numbers and equioment were cleanly
renumbered.
It's is C&W's policy to allow a reasonable amount of time for renumbering.
The policy that was in place when MCI's "logo" was on the network remains
the same. Customers can work out the details by sending email to
ipadmin@cw.net.

Since you appear to have transit from MCI, they should just let you move
those address blocks to your account and avoid renumbering entirely (or at
your leisure to take advantage of multihoming using your address block).
We have done exactly that with several customers that used to be with MCI,
although none since CW took over. They just go change the AS on the route
objects in the MCI RR to yours, and then you can announce them.
We have also done the same thing with a CRL customer, although that was a
much more painful experience since the router configurations are done
manually.
