Of the use of multiple ULA prefixes at a single physical place

I recently understood how ULAs could be useful (so I could very simply transpose my IPv4 gaslighting DNS server setup to IPv6: s!10.28.56.0/24!fdxx:xxxx:xxxx:yyyy::/64!g).

I'm now overthinking it: should my homelab (which has its own VLANs and is in its own rdomain(4) have only their own local part (yyyy) changed or also their own distinct domain part (xx:xxxx:xxxx)?

Current status:

  • Adults VLAN at home: fdxx:xxxx:xxxx:123::/64
  • Guests VLAN at home: fdxx:xxxx:xxxx:58a::/64

Should the homelab be fdxx:xxxx:xxxx:1ab::/64 or something else entirely? (fdzz:zzzz:zzzz:kkkk::/64)

Any insight is appreciated, thanks!
