Well, hard to tunnel to a loopback address, but, using a better example: www IN A 192.0.2.50 IN AAAA 2001:db8::2:50 Would not preclude a tunnel at all. The issue is that he seemed concerned with additional latency from a tunnel resulting in SEO penalties, so, I suggested native as a resolution to that concern. Owen
