said by AVonGauss:If the link-local addresses are consistent for your devices, you could skip the unique local if you don't need routing and just enter the link-local in to your DNS. The downside is you're unlikely to know just by the address what device it is (i.e. not a high chance of remembering each link-local address). If that's not a concern, that's one less addressing scheme to maintain.
I agree. I'm a fan of keeping it simple. IPv6 auto configuration does a lot of work and you can find yourself swimming against the current if you bring some IPv4 thinking over.
