Can't do IPv6 internally or externally? Internally there should be zero need for ~infinite addresses. Externally though I certainly hope all software is capable of operating via IPv6 at this point because otherwise it will only be increasingly broken.
Can't do it externally, kinda. Last year I succeeded in joining a device reachable only through IPv6 to a Netbird network, but their service would fail when I tried to configure IPv6 nameservers for it; the web UI did accept them fine though, they just didn't work. A shame, since I was otherwise fine with IPv4-only for the Netbird network.
