Ask HN: How do you effectively use IPv6 addresses up?

My ISP started assigning /64 blocks to customers (residential) on request, with bigger allotments available, so I was thinking of asking for a block for fun - the question is - how do you effectively use them? Right now I don’t have static V4, but they’ll give me a static V6 block, so I’m converting my DNS server into using static V6 address and ditching v4 (using a 4-to-6 proxy), but aside that I’m not sure what to do, thoughts?
