Yeah - on your local network it seems odd, but
otherwise I guess
there could be differences that make an ipv6 connection better than
an ipv4, or vice versa?
I have been letting Wireshark run for a while. In general, it
alternates IPv4 & IPv6. There have been a few with 2 IPv6 requests in
a row, 1 with 4 IPv6 and 1 with 2 IPv4. What ever it is, it sure
As I said, if I had specified 2 or more addresses, I'd expect them all

Yes, when you only have one host, the lookup may reveal two addresses,
and only if ipv6 somehow yields poor results (not likely on your local
network), might ipv4 be preferred. For that host.
