These VM instances will share the same security group rules.
A security group can be attached to more than one VM instance.The constraints of a security group are as follows: Enter a DHCP IP address, such as 234e:0:4568::3. Gateway: Enter a gateway for the IPv4 network, such as 234e:0:4568::1.Prefix Length: Enter a prefix length for the IPv4 network, such as 64.
End IP: Enter an end IP for the IPv4 network, such as 234e:0:4568:0:ffff:ffff:ffff:ffff. Start IP: Enter a start IP for the IPv4 network, such as 234e:0:4568::2. SLAAC: Stateless address autoconfigurations, which means that interface addresses are automatically deduced via prefixes of routing advertisements, while other parameters are attached in the routing advertisements. Stateless-DHCP: Stateless DHCP configurations, which means that interface addresses are automatically deduced via prefixes of routing advertisements, while other parameters are configured via the DHCP protocol. Only the IP Range method supports this allocation. Stateful-DHCP: Stateful DHCP configurations, which means that interface addresses and other parameters are all configured via the DHCP protocol. Note: IPv6 supports the following IP allocations:
