Redirecting DNS Queries Using a CNAME Pool
Overview: Redirecting DNS queries using a CNAME pool
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.
About CNAME records
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.
