When you want to redirect DNS queries for a web site to a different web site, create a wide IP that represents the original web site, and add a pool configured with a CNAME type to the wide IP with an A record type to redirect the requests to the new destination.
A CNAME record specifies that a domain name is an alias of another domain. When you create a CNAME pool with members specifying the canonical name, BIG-IP DNS responds to DNS name resolution requests for A or CNAME name record type queries with these names if this pool is added to the said wide IP.
Perform these tasks to redirect a DNS request using a wide IP, which includes a pool that is configured with a CNAME type.
You now have an implementation in which BIG-IP® DNS resolves a DNS query for a wide IP to a CNAME.
