    Option
    Description
    NAPTR
    The Name Authority Pointer record, NAPTR, aids in the standardization of Uniform Resource Names (URNs). 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.
    A
    The Address record, or A record, lists the IP address for a given host name.
    SRV
    The Service resource record, SRV, is a pointer with which an alias for a given service is redirected to another domain.
    CNAME
    The Canonical Name resource record, CNAME, specifies an alias or nickname for the official, or canonical, host name.
    AAAA
    The IPv6 Address record, or AAAA record, lists the 128-bit IPv6 address for a given host name.
    MX
    The Mail Exchange resource record, MX, defines the mail system(s) for a given domain.

BIG-IP DNS sends either an A or AAAA record that contains the IP address of a virtual server, or a CNAME record that contains the canonical name for a DNS zone as a response to the requesting client's local domain system server (LDNS).
