FreeBSD 9.0 supports only IPv6. What this practically means?

I have very scarce knowledge of IPv6 but I’m considering installing FreeBSD on an RDC device which acts as a server to my home network running services.
The last release states that one of the changes is IPv6 support only. I don’t quite understand how will this affect my network, other devices etc. Should my ISP support IPv6 in some way in order for me to use FreeBSD etc? I’m also using services like dyndns to connect back to my home server via internet. Will that address respond to IPv6 addresses only?

Answer

Not quite! It still supports both IPv4 and IPv6, but it is now possible, if desired, to build an IPv6-only kernel.

You can still still install FreeBSD with just an IPv4 address. If you obtain an IPv6 allocation you can configure this too.
