Bulk DNS Resolution via Spreadsheet Import for OneIP Table

NetBrain does not currently provide a way to import a spreadsheet of IP addresses and resolve DNS hostnames for entries that are not yet discovered devices in the domain. Users must rely on devices already present in the OneIP Table to obtain hostname resolution, which limits usefulness when planning hardware upgrades or replacements that will reuse existing IP addresses and DNS names. This enhancement proposes allowing users to import a spreadsheet of IP addresses into the OneIP Table workflow so that NetBrain performs DNS resolution against that imported list, independent of device discovery status. Customers preparing for hardware upgrades or IP reassignment would benefit from validating DNS hostname mappings in advance, reducing manual lookup effort and improving planning accuracy.
