Drop OpenDNS due to issue with l.yimg.com. There is a always a long wait or just hang loading yahoo.com and flickr.com
Using Google DNS but they are slow with some of fav site like hardwarezone.com.sg.

/ip dns
set allow-remote-requests=yes cache-max-ttl=1w cache-size=2048KiB \
    max-udp-packet-size=512 servers=\
    208.67.222.222,208.67.220.220,2001:470:20::2


/ip dns
set allow-remote-requests=yes cache-max-ttl=1w cache-size=2048KiB \
    max-udp-packet-size=512 servers=\
    8.8.8.8,8.8.4.4,2001:4860:4860::8888,2001:4860:4860::8844

best so far
/ip dns
set allow-remote-requests=yes max-udp-packet-size=512 servers=\
    109.69.8.34,106.186.17.181,2001:4860:4860::8888,2001:4860:4860::8844,208.67.222.222,208.67.220.220,2620:0:ccc::2,2620:0:ccd::2
