Can I use the same domain on my company network and on the internet?

Can I use the same domain on my company network and on the internet?

Yes. You can configure different DNS answers for your internal network and the internet using an arrangement called “split DNS”. For example, a name can point to a private address for colleagues connected to the company network and a public address for external visitors.

You need an internal DNS service and devices configured to use it. Keep the records required by externally accessible services in the public DNS zone. Test separately from inside and outside the company network. Internal DNS does not replace authentication, firewall rules or a VPN for access to private resources.
