I found an ISP which in 2008 actively 'breaks' IPv6. A Dutch ISP. Observe:

host mail.home.nl
mail.home.nl is an alias for mail.mars.home.nl.
mail.mars.home.nl has address 213.51.146.46
Host mail.mars.home.nl not found: 2(SERVFAIL)
Host mail.mars.home.nl not found: 2(SERVFAIL)

The SERVFAIL is in reaction to the AAAA query that a modern implementation of host does. Which is the wrong answer. In some cases this could be cached as 'does not exist at all' which would lead to end-users thinking Enabling IPv6 breaks stuff. No, stupid software giving wrong answers breaks stuff. Athome Ziggo, please get with the program, pay attention to what is happening on the Internet and un-break your nameserver.
