Quite. I run my main home network behind the first IP (masquerading the LAN devices for general 'net traffic), then have my domain's primary DNS running off a second IP, backup DNS running on a separate server on the third IP, a second domain running off the fourth IP and a general server (web, *arr etc under Proxmox) running on the fifth. I find I'm using IPv6 more than IPv4 now anyway as it's seldom unavailable these days, usually just on hotspots in hospital etc. The cost is on par with 3-4 full VPS with their own associated dedicated IP addresses though, so it's a bit much when you think of it that way.£2 per IP is (unfortunately) quite cheap. Very little reason for a home user to need a block really, and the potential of it costing £16 is enough to make investigating alternatives worth it.
