// DhcpOptions A set of DHCP options. Used by the VCN to automatically provide configuration
// information to the instances when they boot up. There are two options you can set:
// - DhcpDnsOption: Lets you specify how DNS (hostname resolution) is
// handled in the subnets in your VCN.
// - DhcpSearchDomainOption: Lets you specify
// a search domain name to use for DNS queries.
// For more information, see  DNS in Your Virtual Cloud Network (https://docs.oracle.com/iaas/Content/Network/Concepts/dns.htm)
// and DHCP Options (https://docs.oracle.com/iaas/Content/Network/Tasks/managingDHCP.htm).
// To use any of the API operations, you must be authorized in an IAM policy. If you're not authorized,
// talk to an administrator. If you're an administrator who needs to write policies to give users access, see
// Getting Started with Policies (https://docs.oracle.com/iaas/Content/Identity/Concepts/policygetstarted.htm).
