To resolve a DNS query, a Wide-IP definition must include a name, which is what the DNS query will be looking up, and one or more virtual servers to provide the IP addresses to respond to the query. A name is required to identify the Wide-IP being queried, and virtual servers are necessary to map the DNS name to actual IP addresses. Load balancing methods and monitors, while important for overall Wide-IP functionality, are not strictly required to resolve the DNS query itself.
