Hi everyone, I did multiple research and I think I’m almost done but there is something I don’t get it after a thousand video and tutorial, what is my dns name server.
So I have a server in my office, I know my public IP address and I use 8.8.8.8 as dns for my everyday work, on all the videos I saw on YouTube, they have an IP address ( type a ) and they “link” it with the dns records type mx ( this I get it ) but where did they get the “type a” IP ( do I have to request it, is it my public IP, do I have to create it on my office’s server)? Could somebody help me , please ? Thanks in advance

Your IP is your physical address. A number eg: 123.321.23.34

Your A record is a DNS record that points your domain name to your physical address. Eg: example.com -> 123.321.23.34

MX is a DNS record that points to your A record, which in turn points to your physical address. Eg: mail.example.com -> example.com -> 123.321.23.34

And these are normally configured on the DNS of the company that sold you your domain name, but you could also do in on a LOCAL DNS server if you have one installed

Sorry, I’m still confuse, do I use my public IP or my domain provider IP???
Example:
my public IP is 111.111.111.111
My server LAN IP is 192.168.2.2
My domain provider is 99.99.99.99

Which one do I use for the dns records type a???

Thanks

Your A record is your address on the internet.
It needs to be your public IP address.

Thinking about this, how would me knowing your domain provider's IP address find you? Or how would I know which LAN is yours.
The ONLY way that I could find you is your PUBLIC IP address.

You probably will set your A record, and your MX record on the DNS owned by the domain provider via a web interface, although you COULD host your own DNS and NS - but that is a lot of work.

DNS-Servers can be setup for public internet services, for your Company/Organizational needs
or if you need it for your Private Home Network.But only on the public Internet available DNS-Servers can answer queries. If you have a private IP Network, only your private or corporate Users can query your own DNS-Server.

However:
Running a own DNS-Server on the public Internet is a huge responsibility. It needs to be always on and safe fail configured with at least a second insync slave DNS-Server or you wont get the permission by your Domain Registry to run your own known and listed authoritative DNS-Server.
