Subject: So Cal Verizon Business FIOS to Frontier cutover

So the transition from Verizon to Frontier is coming up, and I recently got a notice from Verizon pointing me to the following website:

Evidently one of the things Verizon did not sell to Frontier is their IP address space, as it seems customers with static IP addresses are going to have to change their allocations :(. I have five statics, and while it is not the end of the world, it will certainly be annoying to have to reconfigure not only my equipment but also update the configurations of my clients that access it and the other service providers I access who restrict based on it <sigh>. I was hoping to get some simple additional information regarding this migration, such as:

* How far in advance of the cutover will we be notified?
* How far in advance of the cutover will we be supplied with the new static IP addresses?
* How big will the cutover window be, and will it be attended or unattended?
* How will reverse DNS resolution be handled?

So I called the phone number on the website that was provided for questions or additional information. I'm not quite sure why they provided it, as the person who answered it had absolutely no information to provide other than that that was already on the website, and said they were unable to direct me to anyone who could provide any further information; I guess it was for people who needed the website read to them?

Any chance there is a Frontier engineer on the list who might be able to provide this information, anonymously if necessary :)? Or someone who has gone through a Verizon to Frontier FIOS static IP address transition in another location who might describe their experience with the assumption it will be similar in California?

As far as reverse DNS, the only thing I can seem to find is this:

Which talks about "Business Class DSL and Dedicated Internet" customers, not sure if it applies to FIOS? What I'd really like is to get my PTR entries delegated to me via CNAMEs so I could control the TTLs and update them whenever I wanted to without having to hassle the provider (one of my colleagues has this arrangement with charter business cable), Verizon was never willing to do that.

On another note, does anybody have any idea regarding Frontier's position on rolling out IPv6 for business FIOS :)? Hopefully they won't be quite as archaic and stuck in the mud as Verizon has been on that topic :(.

Thanks much for any info.
