Endpoint Device DNS Resolution
When Cato is handling DHCP and DNS for all devices within an account across multiple vlans, across multiple sites, is it possible for a device to resolve the IP of a hostname outside of the local subnet that the device is on, using Cato DNS to resolve the hostname? We historically have had on-prem Windows AD providing DHCP/DNS which reliably provided name resolution from hostname to IP, but also reverse DNS for IP back to hostname. We are moving to Entra ID/Intune+Auto Pilot managed devices with the outlook to retire our on-prem servers entirely. We have various use cases where we need to resolve a hostname to have the IP returned, but also for the IP to resolve back to hostname via reverse DNS. This has become difficult for Entra ID managed devices unless the device is on the same local subnet where the site switch manages the resolution via the local mac table. Is mDNS the right approach and where I should focus my attention or is there an alternative I should consider? As is looks like mDNS is restricted to vlans within the same site, it may not work in our scenario where we need to resolve across sites. Any advice or recommendations are greatly appreciated.
