cerowrt by default accesses the *ROOT* servers to get it's dns data.
so if that is corrupt or wrong, there's a major issue. It is possible
you are losing on a geo-location basis, however.
If your ISP supports DNSSEC (and is not playing games with DNS) you
can optimize your dns access by using your ISP's provided dns servers
in the forwarders.conf file and uncommenting the relevant line in
What I get for a host www.google.com is:
www.google.com is an alias for www.l.google.com.
www.l.google.com has address 126.96.36.199
www.l.google.com has address 188.8.131.52
www.l.google.com has address 184.108.40.206
www.l.google.com has address 220.127.116.11
www.l.google.com has address 18.104.22.168
www.l.google.com has address 22.214.171.124
www.l.google.com has IPv6 address 2001:4860:800a::63
