 There's always the nice 'n' easy system of using 10/8 and NAT as a 
provider, making renumbering about 5 minutes work.

 Even taken to the extreme, it wouldn't take long to change your BGP 
announcements / have your provider change their BGP announcements / 

 Nameservers are a bit harder to renumber, but that's not too bad.

 Wonder how long it'll be before ISPs rather than corporates start to 
use NAT for most of their network.
