cidrs

The IPv4 address, or range of IPv4 addresses (in CIDR notation) that are allowed to connect to an instance through the ports, and the protocol.

The ipv6Cidrs parameter lists the IPv6 addresses that are allowed to connect to an instance.

Examples:

  • To allow the IP address 192.0.2.44, specify 192.0.2.44 or 192.0.2.44/32.

  • To allow the IP addresses 192.0.2.0 to 192.0.2.255, specify 192.0.2.0/24.
