You will find that most networks filtering /48s allow them from the pool with only /48s in it.
That makes perfect sense.
If you can justify getting a /32, then I suggest you do so, but if not then don't worry, a /48 will work just fine. The networks that do filter you will pretty soon adapt I expect.
I can't in good conscience justify a /32. That is just too much space. I believe I can, however, justify a separate /48 in Europe and APAC with my various offices and data centers in that region coming from the /48 for that region.
Insert routing table explosion religious war here, with snipes from people saying that we need a new routing system, etc. etc.
Eh, it isn't so bad. I could think of some ways things could have been better (e.g. providers use a 32bit ASN as the prefix with a few "magic" destination prefixes for multicast, anycast, futurecast and multihomed end users use a 16-bit regional prefix with a 16-bit ASN as a 32-bit prefix) but we are too far down the road to complain too much about that sort of stuff.
So with that in mind, do your concerns from your original post still make sense?
Thanks, Nathan, and let's say that I am somewhat less apprehensive than I was. George
