Dns reverse lookup zone not updating

The log file for this script will over time get rather large filling up the system partition on your diskstation.

Note: The DNS servers from your ISP may stop working when you change ISP.

Click finish to return back to the main DNS server window.

Open up the log tab and make sure the top two entries are all zones running and running.

You will only really need this if you have some local servers, computers or other devices that need to be accessed. If you need help installing the DNS package do not even try this tutorial you are not ready yet. Learn to swim before jumping into the middle of the river! This is where you configure the lookups, where you know the hostname and want to find the IP address. Note: I use a serial format of the date yyyymmddnn where the last two digits ‘nn’ are just a sequential number for changes I made by hand on a particular day. We also need one A type record for each server or device in our domain. we will need to setup mailserver and the media server running mythtv called mythtvserver.

Once installed and running you will find the DNS icon in the main menu. This serial number is used if you have a backup or slave DNS systems. The NS type record was created already when we created the forward zone. Use the example below to create the others as well.

If they are not set to that, you did something wrong. Point the DNS server setting of a device or PC to your new DNS server and use ping to try out the A, CNAME and MX records we created. This means if you perform the same lookup within a few minutes of each other the DNS does not actually do the lookup it looks in its cache first, it can do this quicker then performing the lookup. Any queries that cannot be resolved need to be forwarded to another DNS server.

If you are running Linux or another proper OS with a dig command you can use that with the full hostname. If not you did something wrong which needs to be fixed before you continue. You can use the following command to find the MX records for a domain. The DNS server will now resolve all our local hostnames to IP addresses. We do that by setting the values in the Resolution tab.
