NAPTR records map between sets of URNs, URLs and plain domain names, and suggest to clients the protocols available for communication with the mapped resource.AThe Address record, or A record, lists the IP address for a given host name.SRVThe Service resource record, SRV, is a pointer with which an alias for a given service is redirected to another domain.CNAMEThe Canonical Name resource record, CNAME, specifies an alias or nickname for the official, or canonical, host name.AAAAThe IPv6 Address record, or AAAA record, lists the 128-bit IPv6 address for a given host name.MXThe Mail Exchange resource record, MX, defines the mail system(s) for a given domain.

- In the Members area, for theLoad Balancing Methodsetting, from thePreferred List, selectRound Robin.When deploying this implementation in a lab environment, to determine whether the BIG-IP system returns the DNS response that you expect, try selecting theGlobal Availabilitymethod and disabling the first pool member in the list.
- In the Members area, for theLoad Balancing Methodsetting, from thePreferred List, selectRound Robin.When you create a pool of one or more packet gateway systems (PGW) systems, it is the best practice to apply the GTP monitor and the round robin load balancing method to the pool. However, the BIG-IP system supports the use of any static load balancing method in this implementation.When deploying this implementation in a lab environment, to determine whether the BIG-IP system returns the DNS response that you expect, try selecting theGlobal Availabilitymethod and disabling the first pool member in the list.
