'www' Subdomain

Tests that an IP address can be found for the 'www' subdomain.

This test will attempt to lookup the IP address for the 'www' subdomain (ie: www.example.com). There should be an 'A' record here that gives the IP address. There could also be a 'CNAME' record that points to another 'A' record. If an IP address cannot be found, then the test will report an error.
