Why each option
This question addresses a common networking challenge when merging companies with overlapping IP address ranges and tests the knowledge of NetApp ONTAP's solution for this, which is IPspaces.
VLANs provide layer 2 segmentation within a single broadcast domain but do not solve the problem of duplicate IP addresses in different routing contexts at layer 3.
Failover groups are used for high availability of LIFs across different ports or nodes and do not address the issue of overlapping IP address ranges.
IPspaces in NetApp ONTAP allow you to create distinct network domains, each with its own routing table and network configuration, enabling the cluster to host multiple clients that use overlapping or duplicate IP address ranges. By using IPspaces, the new company's network can be isolated within its own IPspace, preventing conflicts with existing IP addresses on the cluster.
A DNS zone maps hostnames to IP addresses but does not resolve the underlying problem of duplicate IP addresses within the same routing domain.
