No, you don't. RFC3069.
I deployed one-vlan-per-customer-subvlan with a shared /27 supernet on
Extreme Networks equipment in ~2002, the same thing can be done on Cisco
as well ("ip address unnumbered lo10" and static routes for each /32 to a
specific vlan interface).
This was for a static address assignment model (one static public IPv4
address per customer) for ADSL (ethernet DSLAMs), I'm sure there is the
equivalent for DHCP, I just haven't had the need to deploy it so I haven't
looked into it.
