Another option for simplicity in dual stack is to assign visually similar addresses:

    - ipv4: 192.168.0.42
    - ipv6: prefix:192:168:0:42

I only do this for static/server machines, configuring Linux with a fixed ipv4, and append the fixed ipv6 host to the Router Advertisement prefix.

If I hadn't put my long-running machines' -er- ULA-derived [0] SLAAC addresses into my local DNS ages ago, I'd either do exactly that, or slice off the "redundant" parts of the IPv4 address off, so that I could choose to assign sixteen additional bits of addresses to each host. That is:

  - ipv6: prefix:192:168:0:42

would become

  - ipv6: prefix::0:42:[0-ffff]

[0] I'm really not sure how to succinctly say "The autonomously-configured addresses on my LAN's ULA prefix".
