DNS Zone Standards
Internal DNS zones are, for the most part, simply structured. Majority of systems won't be at the root of the IPA domain (in this case, rockylinux.org). Instead, subdomains are used based on environment (e.g. datacenter) as a starting point, with an additional subdomain that notes the "type" of systems or endpoints.
