/**
 * Container for the parameters to the {@link com.amazonaws.services.ec2.AmazonEC2#createDhcpOptions(CreateDhcpOptionsRequest) CreateDhcpOptions operation}.
 * 
 * Creates a set of DHCP options for your VPC. After creating the set,
 * you must associate it with the VPC, causing all existing and new
 * instances that you launch in the VPC to use this set of DHCP options.
 * The following are the individual DHCP options you can specify. For
 * more information about the options, see
 *  RFC 2132 
 * .
 * 
 * 
 * 
 *  domain-name-servers - The IP addresses of up to
 * four domain name servers, or AmazonProvidedDNS . The
 * default DHCP option set specifies AmazonProvidedDNS . If
 * specifying more than one domain name server, specify the IP addresses
 * in a single parameter, separated by commas.
 *  domain-name - If you're using AmazonProvidedDNS in
 * us-east-1 ,
 * specify ec2.internal . If you're using
 * AmazonProvidedDNS in another region, specify
 * region.compute.internal (for example,
 * ap-northeast-1.compute.internal ). Otherwise, specify a
 * domain name (for example, MyCompany.com ).
 *  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). We recommend that you specify 2 (broadcast and multicast are
 * not currently supported). For more information about these node types,
 * see
 *  RFC 2132 
 * . 
 * 
 * 
 * 
 * For more information about DHCP options, see
 *  DHCP Options Sets 
 * in the Amazon Virtual Private Cloud User Guide .
