But that's where the /35 "pressure" applies because if (say) UKERNA wanted
to offer a /40 to each University it would at present be looking at being
able to connect just 32 Universities. By 2001 there will be over 800
University and further education colleges online under the UK JANET network.
Of course they're not all big, varying from maybe 4,000 to 40,000 people,
so most could live under a /48. At least with the current technology that
lives around us.
I would be interested to know what the addressing requirements of a mobile
provider would be, in terms of scale and subnetting. What would the
"home prefix" of 1,000,000 Vodaphone customers be, for example? I've
not yet seen a draft IPv6 allocation policy for a mobile provider.
