After the report to the Tier 2 support at home (me) from Tier 1 (my son) who had reset the modem, I found that I can't ping the DNS server 75.75.75.75 or 75.75.76.76. At first www.google.com would not ping, but now it is replying with an IPv6 address.

In an ipconfig /all, it is showing both IPv6 and IPv4

When I do a trace to www.google.com, it uses IPv6
It looks like there is a large DNS whole for IPv4.
Has anybody seen anything like this?
