The site has two versions, one for the internal users where internal job postings are available. You can optionally include the IP address . In some circumstances, the Enterprise DNS servers are expected to perform recursive resolution over the Internet for the internal users, while they also must act as authoritative name servers for external users, and block recursion for them.

Using DNS policies these zones can now be hosted on the same DNS server. With the DNS Server tools installed, you can administer DNS records on the managed domain. The same record can be present in multiple scopes, with different IP addresses or the same IP addresses. If you don't have any way of setting it, your best bet would be to use your Pi-Hole device as a DHCP server.
