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).
