What does a Static DNS entry do on a managed switch
So I have read the manual, but if someon could explain in a non-network guys terminology it would help me out a great deal. As stated above I have a GC752X Inisght managed switch. Page 59 in the manu...
Well, the only DNS query happening is for the "web.ddns.net" - from here you hit some NAT or port forwarding to a LAN IP and no more DNS query will happen on the LAN.
The only noteable exception might be if you run some load balancer or application proxy which can work internally on internal FQDNs.
On System > Management > DNS > Host Configuration you can put up FQDN host names to IP address, just like the A (IPv4) resp. AAAA (IPv6) records on a DNS server do - of course just to the standard non-secure DNS.
On the System > Management > DNS > DNS Configuration ... DNS Default Name field, enter the default DNS domain name to be include in DNS queries where only a hostname is provided.
Thanks man!
so please forgive me, I'm not a networking guy so much as a more infrastructure systems guy, meaning I do more on the VMWare and server side of things not so much switching and routing.
My example I'm about to give is really REALLY exact, this switch is something I put in my lab to replace an ancient Cisco 2960 mostly for the 10Gb connections.
I run some internal websites, and I use them with my local domain name "web.domain.local". I used Dynamic DNS service to map it externally to "web.ddns.net", and I have a 1to1 NAT and ACL on my firewall to translate it to my internal web server being "10.50.18.x". When I open up a browser, and go to "web.ddns.net" it routes out to the interwebs, then back into my network. Obviously I'm trying to eliminate some hops if I can.
I entered in the HostName and IP under "DNS Host Configuration" but how do I tell my network machines to look here for DNS? Just add it to the DHCP server as one of the DNS servers? I had tried that but Windows Server says it doesn't see that this server is running DNS as a service or something like that. And as far as I can tell nothing is looking to it anyway even when I add it regardless of that error. Any ideas of what I'm doing wrong here?

ok, so it seems I wont be able to get the NetGear switch to do what I'm looking for, but in case anyone else has something like this in mind, I just set the DNS on the switch to use my PiHole server, and adjusted the PiHole Server host file with the internal entries and all is well. tested that my external is still working as expected using the DDNS.net address.
Thanks schumaku for the help earlier, I be slowly learning netowrk crap!
