When more than one UDP, TCP, or TLS option is available and all are at the same order and preference,
your system considers UDP the highest priority, then TCP, then TLS.
With NAPTR enabled, your system can fail over and fall back among UDP/TCP/TLS transports or change
to a different transport based on the result of each NAPTR lookup, which renews at half of the TTL value
from the DNS server.
This feature complies with RFC 2915.
Enable NAPTR Lookup
