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.

1. On the Main tab, click DNS > GSLB > Pools .
   The Pool List screen opens.
2. Click Create.
3. In the Name field, type a name for the pool.
   Names must begin with a letter, and can contain only letters, numbers, and the underscore (_) character.

   Important: The pool name is limited to 63 characters.
4. From the Type list, select the CNAME type.
5. In the Members area, for the Member List setting, from the Wide IP list, select either a pool member (A or AAAA type) or a static target, and then click Add.
6. Click Finished.

1. On the Main tab, click DNS > GSLB > Wide IPs .
   The Wide IP List screen opens.
2. Click Create.
3. In the Name field, type a name for the wide IP.
   Tip: You can use two different wildcard characters in the wide IP name: asterisk (*) to represent several characters and question mark (?) to represent a single character. This reduces the number of aliases you have to add to the configuration.
4. From the Type list, select a record type to serve from the required DNS query types.
   Note: If you want the BIG-IP^®DNS to respond to both A and CNAME record type requests, you must configure two wide IPs. One wide IP of type A with a CNAME pool type, and a second wide IP of type CNAME with a CNAME pool type. At a minimum, an A record type wide IP should be configured with a CNAME pool.
5. In the Pools area, for the Pool List setting, from the Pool list, select the name of the CNAME pool, and then click Add.
6. Click Finished.

1. On the Main tab, click Statistics > Module Statistics > DNS > GSLB .
   The Global Traffic statistics screen opens.
2. From the Statistics Type list, select Wide IPs.
   Information displays about the cumulative number of DNS name resolution requests processed by the wide IP, and the number of requests load balanced using specific methods.
