Um, lets about this.  You use NAT.  That'll be $180.00 please.  
I'll send you an invoice.

Slack, no. You're comparing apples to oranges here and HOPEFULLY, you know
it.  Basing security on IN-ADDR is absolutely idiotic.  It is VERY easy to
spoof and there's not a damned thing you can do to stop the spoofing.  
Basing security on IP addresses on the other hand is while not a complete
security solution, MUCH MORE SOUND than IN-ADDR.  You can at least build
ACLs in your router(s) that don't allow spoofed traffic to enter your
network.  Now, about the SSL security thing. SSL certification is designed
to certify the identity of the server and that identity is based on the
FQDN.  SSL CERTs are around for the PRECISE reason that it is too easy to
spoof IN-ADDR, etc.

And that's right up there with "<plonk!> me please!  I'm an idiot DSL
monkey!  WAAAAAAAAAA!  My DSL provider went tits-up and I hadn't built any
contengency plan.  I'm going to go bankrupt!  WAAAAAAAAA!"

You got caught with your pants down.  It's that simple.  You're not alone.  
A whole slew of folks went through (or are going through) the same thing.  
The difference is that the VAST MAJORITY of them are NOT bitching and
moaning about it on NANOG about it.


If your business depends (depended) on stable and reliable internet
connectivity with your own (or at least non-changing) address space, might
I suggest that you should have gone to ARIN for a microblock of address
space and established a contengency plan with some other provider(s) in
the event that the sky fell?
