1. Additional VPC Features: Section Context
时间范围：00:00–00:43
总结 / Summary
中文
这一小节说明“附加 VPC 功能”是上一节 VPC 基础知识的延续。课程假设学习者已经具备 AWS 助理级认证（AWS Associate-level Certification）所需的 VPC 基础，因此本节把更贴近高级网络专项认证考试的补充功能单独整理出来。
English
This section explains that “Additional VPC Features” continues the preceding VPC fundamentals. Because the course assumes AWS associate-level knowledge, these supplementary, exam-relevant VPC capabilities are organized into a separate section.
Transcript
00:00 Hi.
00:01 So this small section is like continuation of the previous section that is VPC fundamentals.
00:07 But the reason I pulled out this section separately is because I expect that you already know all those
00:13 VPC fundamentals, because this course expect that you have AWS associate level knowledge.
00:20 But as we explained, we added the previous section just in case somebody is not aware of those basic
00:27 topics.
00:28 And this particular section is more focused on your exam.
00:32 So please go through all this topic of this section because these are essential for your certification
00:39 exam.
00:40 Now this is a very short section as I said.
2. Topics Covered in This Section
时间范围：00:43–01:56
总结 / Summary
中文
本节将覆盖四项内容：用于 IPv6 出站访问的仅出站互联网网关（Egress-only Internet Gateway）；通过辅助 VPC CIDR（Secondary VPC CIDR）扩展地址空间；弹性网络接口（Elastic Network Interface, ENI）及其使用场景；以及将自有 IPv4/IPv6 地址引入 AWS 的自带 IP（Bring Your Own IP, BYOIP）功能。
English
The section covers four topics: the Egress-only Internet Gateway for IPv6 outbound access, expanding address space with secondary VPC CIDRs, Elastic Network Interfaces (ENIs) and their use cases, and Bring Your Own IP (BYOIP) for both IPv4 and IPv6 ranges.
Transcript
00:43 And in this section we will cover few topics.
00:46 And as required I'll add more topic which are relevant for VPC.
00:51 So in this section we will first see egress only internet gateway.
00:54 And this is required for IPv6 traffic.
00:58 Then we will also talk about extending the VPC Cidr ranges.
01:02 So as of now we have just allocated single IPv4 Cidr range.
01:07 But you can also add more Cidr ranges to your VPC.
01:11 So we will see how to do that.
01:13 Then we will dive a little deeper into the elastic network interfaces.
01:17 Because so far we just talked about IP addresses being associated with the EC2 instance.
01:24 But in reality the IP addresses come from the Enis.
01:27 So let's see more functionality about the Enis.
01:31 And finally we will also see how can you bring your own IP address ranges to AWS.
01:38 And this is applicable both for IPv4 and IPv6 IP address ranges.
01:44 Right.
01:44 So in this section let's go through all these topics so that we cover all the basics about VPC for your
01:50 exam.
01:52 So with that let's go to the first lecture of this section.
01:55 Thank you.
整讲总结 / Overall Summary
中文
本讲是“附加 VPC 功能”章节的路线图。它把考试相关的 IPv6 出站网关、辅助 CIDR、ENI 深入功能和 BYOIP 四个主题串联起来，为后续逐项学习建立范围。
English
This lecture is the roadmap for the “Additional VPC Features” section. It scopes the four exam-relevant subjects that follow: IPv6 egress gateways, secondary CIDRs, deeper ENI functionality, and BYOIP.
