dnssrv - Tcl DNS SRV Client
package require dnssrv
::dnssrv::hostlist query ?options?
::dnssrv::tophost query ?options?
The dnssrv package provides a Tcl client for querying DNS SRV records. You should refer to RFC 2782 for information about DNS SRV records.
Return an ordered list of hostnames from a DNS SRV RR recordset resolved
from DNS. Query should be a fully qualified domain name in the form expected
for a DNS SRV record resembling _service._protocol.example.org
The list will be properly sorted and randomized to accommodate the advertised priority and weighting values from the underlying RR recordset in DNS.
The -ports option will append the advertised port number as part of the hostname in the
form hostname.example.org:port
Returns a single hostname which represents the top-ordered host from the hostlist for use where only a single hostname is desired.
