    public final class DhcpDnsOption
    extends DhcpOption
    DHCP option for specifying how DNS (hostname resolution) is handled in the subnets in the VCN.

    For more information, see DNS in Your Virtual Cloud Network.
    Note: Objects should always be created or deserialized using the DhcpDnsOption.Builder. This model distinguishes fields that are null because they are unset from fields that are explicitly set to null. This is done in the setter methods of the DhcpDnsOption.Builder, which maintain a set of all explicitly set fields called DhcpDnsOption.Builder.__explicitlySet__. The hashCode() and equals(Object) methods are implemented to take the explicitly set fields into account. The constructor, on the other hand, does not take the explicitly set fields into account (since the constructor cannot distinguish explicit null from unset null).

    • Method Detail

      • getCustomDnsServers

        public List<String> getCustomDnsServers()
        If you set serverType to CustomDnsServer, specify the IP address of at least one DNS server of your choice (three maximum).
        Returns:
        the value
      • getServerType

        public DhcpDnsOption.ServerType getServerType()
        • VcnLocal: Reserved for future use.

        **VcnLocalPlusInternet:** Also referred to as "Internet and VCN Resolver". Instances can resolve internet hostnames (no internet gateway is required), and can resolve hostnames of instances in the VCN. This is the default value in the default set of DHCP options in the VCN. For the Internet and VCN Resolver to work across the VCN, there must also be a DNS label set for the VCN, a DNS label set for each subnet, and a hostname for each instance. The Internet and VCN Resolver also enables reverse DNS lookup, which lets you determine the hostname corresponding to the private IP address. For more information, see [DNS in Your Virtual Cloud Network](https://docs.oracle.com/iaas/Content/Network/Concepts/dns.htm).

        **CustomDnsServer:** Instances use a DNS server of your choice (three maximum).

        Returns:
        the value
      • toString

        public String toString​(boolean includeByteArrayContents)
        Return a string representation of the object.
        Overrides:
        toString in class DhcpOption
        Parameters:
        includeByteArrayContents - true to include the full contents of byte arrays
        Returns:
        string representation
