Sure. However, if the foo.com server has _both_ v4 and v6 addresses, then you could also reach it through v4. Furthermore, the .com server knows this, because you reached the .com server through v4. So why should the .com DNS server bother giving you _both_ v4 and v6 addresses for the foo.com DNS server? What exactly is the benefit that outweighs the cost of building and sending larger packets? Let me emphasize again that we're talking about DNS server addresses in delegations, not about HTTP server addresses. ---D. J.
