I almost guarentee that the Subject line should be better phrased...<br>
<br>
In any event... I has been long enought since I needed to much with DNS type stuff that if I ever knew the answer, I have forgotten that I knew. I need/want to locate _all_ of the public internet facing machine names of my employer in order to locate the correct URL address for what I need to do. (Yes - asking support is feasable, but they are over loaded and I know that the machine name is related to the service I want)<br>
<br>
An example might help (I hope so at least). Say I want to get into the old Moodle system (which is being retired, but isn't shut down quite yet). Is it <a href="http://moo1.myschool.edu" target="_blank">moo1.myschool.edu</a>, <a href="http://moodle1.myschool.edu" target="_blank">moodle1.myschool.edu</a>, <a href="http://oldmoo.myschool.edu" target="_blank">oldmoo.myschool.edu</a> or some other variant? I don't need/want the IP addresses, but the machine names.<br>
<br>
Support people at work are sadly overloaded, so response times are rising at the moment. I'd like to be able to dig my way out of this challenge.<br>
<br>
So far - I haven't asked the Google a correctly formed question to return anything semi-useful in the first 100 + responses. I have looked at the dig man page, and that seems like it should work, but haven't managed to wrap my head around things yet.<br>
<br>
Thankyou one and all for the use of your bandwidth!<br>
