Ipv6Range

Structure Class

Ipv6Range dataclass

Bases: _SerdeShape

Describes an IPv6 address range.

Attributes

cidr_ipv6 class-attribute instance-attribute 
cidr_ipv6: str | None = ...

The IPv6 address range. You can either specify a CIDR block or a source security group, not both. To specify a single IPv6 address, use the /128 prefix length.

Note

Amazon Web Services canonicalizes IPv4 and IPv6 CIDRs. For example, if you specify 100.68.0.18/18 for the CIDR block, Amazon Web Services canonicalizes the CIDR block to 100.68.0.0/18. Any subsequent DescribeSecurityGroups and DescribeSecurityGroupRules calls will return the canonicalized form of the CIDR block. Additionally, if you attempt to add another rule with the non-canonical form of the CIDR (such as 100.68.0.18/18) and there is already a rule for the canonicalized form of the CIDR block (such as 100.68.0.0/18), the API throws an duplicate rule error.

description class-attribute instance-attribute 
description: str | None = ...

A description for the security group rule that references this IPv6 address range.

Constraints: Up to 255 characters in length. Allowed characters are a-z, A-Z, 0-9, spaces, and ._-:/()#,@[]+=&;{}!$*
