Subnet & CIDR
010-计算机网络-无分类编址CIDR
ToolRouting Table
[实际中没有看到路由器,只有路由表]
路由表概述 阿里云 有例子Security Groups & Network ACLs [1]
- Security Groups
EC2 level-工作在EC2 instance level
stateful firewall - Network ACLs
工作在subnet level
stateless firewall
- Security Groups
NAT Gateway && NAT Instance [1]
- NAT Gateway
[通过internet gateway,访问外网, 外网访问不到内部, 多对一] - NAT Instance
- NAT Gateway
Internet Gateway
[一对一的, 静态ip绑定到internet gateway, 外网访问内网的EC2]弹性网络接口ENI[2]
- 弹性网络接口必须有一个主要的私有 IPv4 地址,并且始终与至少一个安全组相关联。
- 弹性网络接口可以在运行时(热连接)、停止时(热连接)或启动时(冷连接)连接到实例。
- 不能分离主网络接口。
- 弹性网络接口仅限于单个可用区。

Bring your own IP addresses (BYOIP)#
Bring Your Own IP (BYOIP) enables customers to move all or part of their existing publicly routable IPv4 or IPv6 address space to AWS for use with their AWS resources. Customers will continue to own the IP range. Customers can create Elastic IPs from the IPv4 space they bring to AWS and use them with EC2 instances, NAT Gateways, and Network Load Balancers. Customers can also associate up to 5 CIDRs to a VPC from the IPv6 space they bring to AWS. Customers will continue to have access to Amazon-supplied IPs and can choose to use BYOIP Elastic IPs, Amazon-supplied IPs, or both.
