Hi Oliver,

I second Ken's notion. You're trying to be an ISP under the end-user rules.
However transient, your users are mostly customers rather than staff. Just
register as an ISP and get the default /32.

IIRC, ARIN sparsely allocates IPv6 so if you go back for more addresses
there is a high probability they'll just increase your netmask.

Finally, /56 or /60 per guest, not /64. IPv6 can do nifty IoT things like
collecting all of a guest's devices behind his personal firewall but it
doesn't work if you've only assigned a /64.

Regards,
Bill Herrin
