From the perspective of remote systems (ie. not on the same network), there is about a 100% chance NAT is involved making it near impossible to individually identify a specific machine, even if it gets the same address every Tuesday when you're at Starbucks for coffee. IPv6 does away with NAT (or it's supposed to); in doing so, the veil is removed and everything that had been hidden from site is now openly displayed. If the "host" part of your address never changes, then you are instantly identifiable everywhere you go, with zero effort, forever.
Use random addresses, and change as often as you like. Why depend on someone else's DHCP server to provide you the addressing uniqueness you desire? -- Dan White BTC Broadband
