Synopsis

Properties

DomainName	This value is used to complete unqualified DNS hostnames.
DomainNameServers	The IPv4 addresses of up to four domain name servers, or `AmazonProvidedDNS` .
Ipv6AddressPreferredLeaseTime	A value (in seconds, minutes, hours, or years) for how frequently a running instance with an IPv6 assigned to it goes through DHCPv6 lease renewal.
NetbiosNameServers	The IPv4 addresses of up to four NetBIOS name servers.
NetbiosNodeType	The NetBIOS node type (1, 2, 4, or 8).
NtpServers	The IPv4 addresses of up to four Network Time Protocol (NTP) servers.
Tags	Any tags assigned to the DHCP options set.

Properties

DomainName

This value is used to complete unqualified DNS hostnames.

string? DomainName { get; }

Property Value

string

Remarks

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 ).

See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-dhcpoptions.html#cfn-ec2-dhcpoptions-domainname

DomainNameServers

The IPv4 addresses of up to four domain name servers, or AmazonProvidedDNS .

string[]? DomainNameServers { get; }

Property Value

string[]

Remarks

The default is AmazonProvidedDNS . To have your instance receive a custom DNS hostname as specified in DomainName , you must set this property to a custom DNS server.

See: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-dhcpoptions.html#cfn-ec2-dhcpoptions-domainnameservers

Ipv6AddressPreferredLeaseTime

A value (in seconds, minutes, hours, or years) for how frequently a running instance with an IPv6 assigned to it goes through DHCPv6 lease renewal.

double? Ipv6AddressPreferredLeaseTime { get; }

Property Value

double?

Remarks

Acceptable values are between 140 and 2147483647 seconds (approximately 68 years). If no value is entered, the default lease time is 140 seconds. If you use long-term addressing for EC2 instances, you can increase the lease time and avoid frequent lease renewal requests. Lease renewal typically occurs when half of the lease time has elapsed.
