      • resolveIpAddress

        public java.lang.String resolveIpAddress​(java.lang.String hostname)
        Deprecated.
        Description copied from interface: DnsResolver
        Resolves the IP Address (A record) to the specified host name. Throws DnsEntryNotFoundException if there is no record.
        Specified by:
        resolveIpAddress in interface DnsResolver
        Parameters:
        hostname - The hostname for which you need the IP Address
        Returns:
        IP Address as a String

      • resolveServiceEntry

        public java.lang.String resolveServiceEntry​(java.lang.String serviceType,
                                            java.lang.String domain)
        Deprecated.
        Description copied from interface: DnsResolver

        Resolves the host name for the specified service in the specified domain

        For example, if you need the host name for an LDAP server running in the domain springsource.com, you would call resolveServiceEntry("ldap", "springsource.com").

        The DNS server needs to provide the service records for this, in the example above, it would look like this: 

         _ldap._tcp.springsource.com IN SRV 10 0 88 ldap.springsource.com.
        The method will return the record with highest priority (which means the lowest number in the DNS record) and if there are more than one records with the same priority, it will return the one with the highest weight. You will find more informatione about DNS service records at Wikipedia.
