Yes - the same as in IPv4, just configure more than one server, each with the same subnets but with non-overlapping ranges. Adjust your lease times to balance being able to "ride out" short server outages (and hence client address changes) which favours long lease times, with the ability to recover leases and/or change things which favours short lease times.
