I&#x27;ve also noticed this. My home ISP (Internode, RIP) provides an IPv6 range. I dutifully set up AAAA records for a couple of my servers and then ended up disabling them either on the client or server side as things as simple as SSH were timing out. I don&#x27;t <i>think</i> it was DNS, I&#x27;m fairly sure there was an MTU issue but I didn&#x27;t dig into it that much.
