NAPTR / SRV are most commonly used when all you have is a "domain name"
and you need to determine the hostname and port associated with a
particular service at that domain (e.g. a SIP server)

I would therefore expect that given a specific hostname and port that
those would be used directly, rather than using NAPTR / SRV.
