Mark is correct=85 It is the ISP=92s poor decision in these cases that =

That=92s not as true as you want to believe it to be.
While /48s are not scarce globally, there is a significant cost to going =

As such, ISPs are going to be motivated not to treat blocks as =

You=92ll get over that eventually. Once you get some experience with the =
