DNS resolution time and failure rate (UDP)

Supported clients: Whiteboxes, Routers

This test measures the DNS resolution time of a selection of common website domain names. These tests will be targeted directly at the ISPs recursive resolvers. A list of appropriate servers will be sought from each ISP in advance of the tests for manual configuration or it will use the default DNS servers in use on the router.
