Dns not updating

10-May-2017 23:33

I ran a DDNS report, and all the DNS servers are pointing to a now defunct address.The only way I can update it is to re-do the port forwarding rule with the name assignment. It automatically connects using an Open VPN config file, but is otherwise untouched.I have checked the event viewer logs for the DHCP and DNS server but nothing is present? I have a basic Apache server running behind my VPN, which forwards the necessary ports and assigns a DDNS name to the exit IP.The PTR is really annoying but not critical but the fact that we often end up with duplicates or incorrect A records is much more problematic.

When you make a DNS change, it takes time for the changes to take effect. It is the time it takes for the domain DNS to refresh the cache on the network.If the ping and traceroute test show your server with us in the outcome, you know the DNS is propagated. You can try speeding up the propagation time by having your TTL set to a lower number (not recommended). We set the default TTL to 14400 (4 hours); however the network that you are using to access the internet may update at a slower rate.You can try Clearing your DNS cache or "Hello siva, and thanks for the comment.Clients are mostly Windows 7 machines with a few XP and Vista.The DHCP server is setup to always update both A and PTR record.

Here is what's going on: We acquired a company a few months ago and I have transferred their registered domain it to our registrar and updated the nameservers with my external DNS provider. Connect to an internal server and see what IP it returns for the domain in question.
