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.
ec2_create_dhcp_options(DhcpConfigurations, TagSpecifications, DryRun)
A list with the following syntax:
list(
DhcpOptions = list(
DhcpConfigurations = list(
list(
Key = "string",
Values = list(
list(
Value = "string"
)
)
)
),
DhcpOptionsId = "string",
OwnerId = "string",
Tags = list(
list(
Key = "string",
Value = "string"
)
)
)
)
[required] A DHCP configuration option.
The tags to assign to the DHCP option.
Checks whether you have the required permissions for the action, without
actually making the request, and provides an error response. If you have
the required permissions, the error response is DryRunOperation
.
Otherwise, it is UnauthorizedOperation
.
