[TriLUG] OT: IP subnetting question

I'm all for future planning, but seriously, when will it become painful?

I have my public IPv4 address(es) and all my service providers have theirs.
Do you really expect any major service providers to stop providing their
services over IPv4 networks any time soon?  

The way I see it, it's not going to become "painful" until IPv6 becomes
prevalent enough for service providers to turn off their IPv4 services.
Just because IPv4 runs out of address space doesn't mean all the existing
IPv4 networks will stop working.

When IPv4 /stops working/, then we'll have a problem.  I honestly can't
imagine that moment coming in, say, the next three years.

Furthermore, negotiating contracts now that will last for years into the 
future is the perfect time to be bringing that up. If you don't do it 
now, things are going to be painful down the road.
