I have never bothered about the svc:/network/dns/client:default
In fact it is disabled on most Solaris 10 boxes; not needed.
It is not a service, just a status that can be used as a requirement for other services.

Code:

# svcs -l svc:/network/dns/client:default
fmri         svc:/network/dns/client:default
name         DNS resolver
enabled      false
state        disabled
next_state   none
state_time   Sat Sep 26 19:26:57 2015
restarter    svc:/system/svc/restarter:default
dependency   require_all/none svc:/system/filesystem/minimal (online)
dependency   require_all/none svc:/network/service (online)
dependency   require_all/none file://localhost/etc/resolv.conf (online)
dependency   require_any/error svc:/network/loopback (online)
dependency   optional_all/error svc:/milestone/network (online)

The following does the libc host resolving (just like ping, but without doing a ping)

Code:

getent hosts www.unix.com

The Linux resolver queries all nameservers in the order they are listed in /etc/resolver.conf. If a nameserver times out, it advances on to the following nameserver. But, if a nameserver returns "not found" (NXDOMAIN) it stops. This behaviour is problematic when you need to resolve names from...

NAME

       Net::DNS::Mailbox - DNS mailbox representation

SYNOPSIS

	   use Net::DNS::Mailbox;

	   $mailbox = new Net::DNS::Mailbox('user@example.com');
	   $address = $mailbox->address;

DESCRIPTION

       The Net::DNS::Mailbox module implements a subclass of DNS domain name objects representing the DNS coded form of RFC822 mailbox address.

METHODS

   new
	   $mailbox = new Net::DNS::Mailbox('John.Doe@example.com');
	   $mailbox = new Net::DNS::Mailbox('John Doe <j.doe@example.com>');

       Creates a mailbox object which represents the DNS domain encoded form of the mail address specified by the character string argument.

       The argument string consists of printable characters from the 7-bit ASCII repertoire.

   address
	   $address = $mailbox->address;

       Returns a character string containing the RFC822 mailbox address corresponding to the encoded domain name representation described in
       RFC1035 section 8.

DOMAIN NAME COMPRESSION AND CANONICALISATION

       The Net::DNS::Mailbox1035 and Net::DNS::Mailbox2535 subclass packages implement RFC1035 domain name compression and RFC2535
       canonicalisation.
