I’ve come across a few questions that I need to resolve for myself concerning DNS, ipconfig or firewall rules, i’m going to try to group these together in a sensical manor but given that they are kind of all different the flow might not be perfect.
Diving into the first question I have on my list:
This is a very good and logical question that, I as person responsible for maintaining a network, should know. Unfortunately I don’t. I would be less dismayed by the fact that I didnt know this if it was just a one off question about an obscure firewall rule but thats
not the case here but as you can see the answer configure windows firewall.
The next step here is to look up some more information on this problem and see if we can figure out more information on how to set this up. It sounds in theory to be very similar to secure DNS updates but this is something completely different. Unfortunately google is no help so we may have to chalk this one up to experience.
Another question that’s really simple if you have enough experience to know exactly what is going wrong, this sort of break/fix logic isnt normally found in training material:
Apparently we are supposed to understand that there are stale records and we simply need to flush the cash I found this video and as you can see the user also goes through ipconfig /flushdns so maybe I wasnt horribly off in my line of thought.
Personally I dont find ip4 to 6 or vice versa questions to be overly complicated as its kind of just a matter of what goes where rather than needing a pool of experience to work through break fix scenarios or something of that nature. I decided to include them in this
for good measure I suppose:
This is really straight forward to me but im going to put a training video for understanding teredo here as well as the other transition technologies.
These sorts of questions I do find hard because I feel like there’s possibly a measure of experience coupled with a deeper understanding of DNS than I currently possess.
Im honestly not sure where to start to find information on this, its too complicated for the basic websites that tell you what does what with DNS record types. I think the logic in the answer explains its self which in that case provides for the idea that we should better
understand ptr record uses and forward lookup zones. In my thought of they basic definitional sites may not be enough I could be faulting on myself for not completely grasping the whole concepts. Im sure its just a matter of time though. Lots to learn!
At first I was absolutely convinced that DNS was crafted by wizards that live in castles using eyes of newts and things like that. I think I’ve moved on (only slightly) from this concept as Ive grown to kind of understand it. I found this lecture series that im currently watching and Ive also found this website to be extremely helpful
