My ISP does this right (provides a /56 for routing), but unfortunately both are dynamic and change periodically. Every time I disconnect and reconnect from the internet, I get a different prefix.

I ended up needing to have ULAs for devices where I need to know the IPv6 address on my network (e.g. my internal DNS servers).

    Indeed, that's correct ula usage, but shouldn't need nat rewriting. The global prefixes just need to be advertised by RA packets

    I use openwrt on my home network which uses dnsmasq for dhcp. It can give a static suffix which just works with the global prefix on the interface and the site local / ula prefix it uses
