That is exactly the right way to count ;)





Which kind of makes the point, that they deserve the /32




Well, apparently RIPE thinks they do, so there must be some piece of
information that I'm not privvy to.



However, in the absense of that particular piece of information, I have
a hard time seeing how the BBC qualifies for a /32. Last time I
checked, they weren't an ISP. 200 sites doesn't qualify you for a /32:
it qualifies you for a /48 (jusst like one site does). That's 65536
subnets = ~300 subnets per site. If that's not enough, perhaps a /47 or
/46 is in order, or maybe, just maybe a /40 = a /48 per site. But a /32
is ridiculous: this allows for 4 billion subnets (20 million per site).



Here is a quote from the "IPv6 Address Allocation and Assignment
Policy" (http://www.iana.org/ipaddress/ipv6-allocation-policy-26jun02
):



5.1.1. Initial allocation criteria



To qualify for an initial allocation of IPv6 address space, an

organization must:



a) be an LIR;

b) not be an end site;

c) plan to provide IPv6 connectivity to organizations to which it

will assign /48s, by advertising that connectivity through its

single aggregated address allocation; and

d) have a plan for making at least 200 /48 assignments to other

organizations within two years.
