DHCP Option Sets¶
A DHCP options set is a set of network configurations that will be delivered to your VM instance when its interface acquires an IP address using the DHCP protocol.
DHCP options sets are associated with a project so that you can use them across all of your virtual private clouds (VPC).
The supported options for a DHCP options set are as follows:
Domain-name-servers - The IP addresses of up to four domain name servers, or ZadaraIaaSProvidedDNS. The default DHCP option set specifies ZadaraIaaSProvidedDNS. Although the custom DNS server is used, the DHCP-supplied DNS server to the VM instances will always be ZadaraIaaSProvidedDNS and the custom DNS will be queried indirectly by ZadaraIaaSProvidedDNS.
Domain-name - This value is used to complete unqualified DNS hostnames. This is set by default to ‘symphony.local’.
NTP-servers - The IP addresses of up to four Network Time Protocol (NTP) servers.
Netbios-name-servers - The IP addresses of up to four NetBIOS name servers.
Netbios-node-type - The NetBIOS node type (1, 2, 4, or 8).
Creating a DHCP Option Set¶
To create a DHCP Option Set:
Navigate to the Networking > DHCP Option Sets view.
From the top toolbar, click Create.
In the Create DHCP Options dialogue, enter the following in the appropriate tab.
Name - name of the DHCP Options Set.
Description - optional description of the DHCP Options Set.
DNS Domain - valid DNS domain name (e.g. xxx.com)
DNS Servers - IP of DNS Server associated with DHCP Options set being defined. Definition of DNS Server is optional.

Netbios Node Type - The following types may be selected:
Type 1 - B-Node
Type 2 - P-Node
Type 4 - M-Node
Type 8 - H-Node
DHCP Options Set Operations¶
After creation of a DHCP Options Set, it will be displayed in the list in the Networking > DHCP Options Set view. The following operations can be performed by selecting a DHCP Options Set from the list, and clicking the appropriate icon from the top toolbar:
Modify - change name of the DHCP options set.
Attach VPC - attach DHCP options set to VPC.
Detach VPC - detach DHCP options set to VPC.
