That’s exactly what prefix delegation is for. Your ISP ought to give an /56 or more, so you can then have multiple /64. I get an /56 by my ISP and have 6 or so

I get an /56 by my ISP and have 6 or so different /64 in my residence.
- simoncion 2y agoSadly, I've only ever gotten /60s. 16 subnets is better than zero, but it's far less than 256.
- f_devd 2y agoISPs do give enough where I am the issue is usually when you are behind 2 firewalls past that or have VMs that you want to DHCP, things like that. A real world example my ISP provides /56 at the router level but if you put a firewall behind it, that gets a /64 (cannot be changed). Now the firewall cannot further delegate prefixes since it's already used. Some firewalls allow RA pass-through but in my case this wasn't an option so I had to set up NAT66 (non-standard :/) just to get outbound ipv6 connectivity.
