0N/A/**
0N/A * A DnsUrl represents a DNS pseudo-URL of the form
0N/A * <pre>
0N/A * dns://[host][:port][/[domain]]
0N/A * or
0N/A * dns:[/][domain]
0N/A * </pre>
0N/A * The host names a DNS server. If the host is not provided, it
0N/A * indicates that the underlying platform's DNS server(s) should be
0N/A * used if possible, or that "localhost" should be used otherwise. If
0N/A * the port is not provided, the DNS default port 53 will be used.
0N/A * The domain indicates the domain name of the context, and is not
0N/A * necessarily related to the domain of the server; if it is not
0N/A * provided, the root domain "." is used. Special characters in
0N/A * the domain name must be %-escaped as described in RFC 2396.
