It is happening. Conventional IPs will run out in less than 2 months from now. After that we might get by another year, by using the IPs we have more efficiently. Still the only long-term solution is to switch to the new IP-protocol version 6.
I'm proud to announce that since today the snapdragon-servers are fully IPv6-ready. That means webserver, mailserver and IMAP. You shouldn't notice any change, since IPv4 is still on as well.
If you would like to see whether you're viewing an v4 or v6-address, you could install this Firefox-plugin or start Chrome with the option --prefer-family=IPv6 or simply browse to the IPv6-version of Google.
