Discovery Job - Domain Overlap

IP range overlap in domains: IP range duplicates are allowed in different domains. Be cognizant about adding the same IP ranges to multiple domains as the identification rule for an IP address includes the domain name in the ID criteria. Therefore, there is a strong possibility of creating duplicate IP addresses.

Also jobs like HMC, VCenter connections should be managed efficiently in the respective domains. If you have a VCetner which provisions servers in different domains, you may end up with duplicates on IP Address layer.
