getObject() {
	return new SRVRecord();
}
Server Selection Record  - finds hosts running services in a domain.  An
SRV record will normally be named _&lt;service&gt;._&lt;protocol&gt;.domain
- examples would be _sips._tcp.example.org (for the secure SIP protocol) and
_http._tcp.example.com (if HTTP used SRV records)
