+1 on this.
We returned our /32 that we received back in 2002 or so, and after proper
application received a /25 where I believe we have up to /22 reserved for
us in case we need it.
We hope we're not going to have to pollute the DFZ with more than a single
entry in the forseeable future.
To everybody who thinks we need to conserve addresses, please consider
this current allocation policy (/48 and /56) as something we'll do for the
first /3 in use, when we exhaust that, we need to really look at what
we're doing and look if we need to change the policy for the other /3:s.
We have 7 more tries to go before we exhaust the whole IPv6 space.
