I have an IPv6-only network. Will the probe work on it?

Yes. All probes can be configured statically with an IPv6 address, default router, DNS resolvers, etc. through the web UI. In addition, version 3 probes can be fully configured through router advertisements (support for RFC 6106 was added in firmware release 4680). There is at the moment no support for DHCPv6 (RFC 3315). Version 1 and 2 probes can obtain addresses and default routers through router advertisements, but cannot obtain DNS resolvers that way. For those probes, the DNS resolvers will have to be configured statically through the web UI.
