dnsdig
A little script using dig or drill to measure response times of DNS resolvers.
Options
A few extra options are avilable in the form of environment variables.
DOMAIN=any.url Can be used to change the domain used for lookups.
TESTDNS=X.Y.Y.Z Can be used to test a resolver IP not already featured.
SKIP=1 Will skip the preliminary message as well as all queries except $CURRENTDNS and $TESTDNS if defined.
