Built-in name resolution, address management, and PXE boot
Tophan runs integrated DNS and DHCP services for your virtual infrastructure. VMs get addresses, register their hostnames, and resolve each other — all managed from Dragon’s Eye without a separate appliance or service to maintain.
DHCP assigns addresses from defined pools with per-network options (gateway, DNS, NTP, custom options). Static reservations bind specific MACs to fixed IPs. Lease data is visible in Dragon’s Eye with search and export.
DNS provides authoritative resolution for internal zones and recursive resolution for external queries. When DHCP assigns an address, the DNS record is created automatically. DNS sinkhole functionality blocks known malicious or unwanted domains at the resolver level — configurable block lists with override capability.
PXE boot support lets you network-boot bare metal or VMs from Tophan-served images, useful for automated OS deployment and diskless thin clients.
