For Abiquo private, external and public networks, the platform can manage their corresponding VLANs with an ISC DHCP server. Abiquo recommends one DHCP server per physical datacenter. Add the DHCP service to Abiquo when creating or editing a datacenter. You  You can use the Remote Services DHCP server supplied with Abiquo or another compatible server. If you have many virtual networks, you might need a separate relay server to manage VLANs for the DHCP server. For unmanaged networks, you do not need to configure a DHCP server and you must provide the network addresses to the virtual machines outside of Abiquo.

How Abiquo uses DHCP

The connections in DHCP are as follows:

1. When you deploy a virtual machine, Abiquo (Remotes Services) supplies the network settings for the new VM to the DHCP Server.
2. When the new virtual machine powers on, it broadcasts a DHCP request for network configuration.
3. The hypervisor passes the DHCP request through a VLAN to the DHCP server.
4. The DHCP server broadcasts a lease with the network configuration for the virtual machine over the same VLAN
