Spam Control Considered Harmful

Perhaps in the UK there are different requirements for allocation of address
space than InterNIC/ARIN.

In the UK, as in the rest of Europe, IP addresses are allocated from
the same finite pool of IPv4 space you use. That's one of the reasons
that InterNIC/ARIN and its counterpart regional registry in Europe,
the RIPE NCC, as well as APNIC, have maintained contact and
cooperation over a long period; working to identical goals, they
haves developed broadly similar policies on address allocation.

It is encouraging to see that policy reflected in sensible
practices such as yours, and to see that it has payoffs in
terms of the economies of address usage, with growing numbers
of customers, that can be achieved.
