Description: Overlapping zones occur when two DNS zones share the same domain names. This can happen in situations where different DNS administrators manage zones that include the same domain, leading to conflicts and ambiguities in name resolution. Overlapping zones can complicate DNS record management, as the system must determine which zone has the authority to resolve a specific query. These zones can be intentional, as in complex network configurations where redundancy is required, or unintentional, resulting from configuration errors. Identifying and resolving these overlaps is crucial to ensure that DNS queries are resolved correctly and that the services associated with those domains operate without interruption. Proper management of overlapping zones involves careful planning and a clear understanding of the name hierarchy in the DNS system, as well as the name resolution policies that apply in a given network environment.
