Re: Selling IPs?
Ownership is fuzzy, viz. the sale of Lucent's to Microsoft and others. Some of the original blocks were, it seems, entirely allocated to individual entities including companies.
But it's dangerous precedent to set for the state to try and sell them and, thus, effectively legitimate the trade. The consequences of open trade in ip addresses (in real time, why not) could be disastrous: it would be akin to reallocate road names and numbers in real time!
In any case while the 30 million might seem like a lot, they could be gone in a trice with IoT in any government department.
And, should it ever come to selling the damn things, their value well decline even further as it becomes cheaper to adopt IPv6 with 4to6. In the meantime the UK's tech sector is losing out by not gaining experience with IPv6, especially in the area of security. Maybe they're waiting for GCHQ to signal that they know how to snoop IPv6 traffic?
