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. To have your instance receive a custom DNS hostname
as specified in domain-name, you must set domain-name-servers
to a custom DNS server.
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, ExampleCompany.com). This
value is used to complete unqualified DNS hostnames. Important: Some Linux
operating systems accept multiple domain names separated by spaces. However, Windows
and other Linux operating systems treat the value as a single domain, which results
in unexpected behavior. If your DHCP options set is associated with a VPC that has
instances with multiple operating systems, specify only one domain name.
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.
Your VPC automatically starts out with a set of DHCP options that includes only a
DNS server that we provide (AmazonProvidedDNS). If you create a set of options, and
if your VPC has an internet gateway, make sure to set the domain-name-servers
option either to AmazonProvidedDNS or to a domain name server of your
choice. For more information, see DHCP
options sets in the Amazon Virtual Private Cloud User Guide.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginCreateDhcpOptions and EndCreateDhcpOptions.
