A command-line tool to send requests to nameservers in a TCP-network/internet
and display the response.
----
If you ever wanted to know which SMTP-server your e-Mails go to
when you sent them to "name@xyz.com", this is the tool for you:
Type "dnstool xyz.com MX" and the server(s) will be displayed.
NOTE: the SMTP-servers will NOT necessarily be xyz.com or www.xyz.com!
In addition, other nameserver-queries are supported, especially:
"dnstool www.xyz.com A" to determine the address of a domain.
For frequent use, it is recommended that you use the tool with
your provider's nameserver, which should be known to you:
"dnstool ftp.xyz.com A ns.myprovider.com" or
"dnstool ftp.xyz.com A 123.123.123.123"
Requirements:
a bsdsocket.library-compatible TCP-stack such as AmiTCP
License:
Freeware, source-code is included
For further information, see the usage-printout of the tool.
For detailed information about the nameserver-protocol, see
the included rfc-document.
