For system administrators, knowing the IP address of your machine, server, or customer’s PC is imperative. This allows you to verify that the IPv6 address has been assigned properly in case you have connection issues.In most circumstances, the majority of users don’t need to worry about their “IP Address” due to DHCP from your local network or ISP. However, if you keep the virtual machine and just reboot or stop the EC2 instance, the IPv6 address of your instance won't change.īy the way, another difference between elastic IPv4 addresses and public IPv6 addresses is that you can see the IP address in the guest OS. This can be a problem if you want to move your application to a completely new instance and you don't want to go through the hassle of changing DNS records, which always causes outages. The downside is that once you terminate the EC2 instance, the IPv6 address is lost for you.

That is, Amazon doesn't have to worry that their AWS customers start hoarding IPv6 addresses, which would be a problem with IPv4.

The reason is probably that Amazon can't charge for an IPv6 address because no shortage exists as for IPv4 addresses. There are no elastic IPv6 addresses, which means that you can't reserve an IPv6 address in AWS. You've probably noticed that assigning a public IPv6 address works differently in AWS than with IPv4 addresses. IPv6 query with nslookup Elastic IP Address for IPv6?

I will assume here that you already have an EC2 instance with properly configured IPv4 settings. That's quite a list for such a simple task, isn't it? Assigning the IPv6 address Here, you define which external TCP (and ICMP) packets are allowed to access your EC2 instance. Security Group-This is Amazon's term for a network firewall. Every EC2 instance has at least one network interface. Network Interface-Everything in the cloud is virtual, including network interfaces. The internet gateway is attached to the VPC. Internet Gateway-This is the virtual router that will accept those packets with an external destination. The route table is assigned to the VPC and determines the next destination for these packets. Route Table-IP packets that need to be delivered to different subnets than the originating subnet (the internet, for instance) need to be routed. You can house several subnets in your VPC. It essentially defines which IP addresses count as local and are therefore switched instead of being routed. Subnet-A subnet is a logical division of an IP network. Virtual Private Cloud (VPC)-Think of a VPC as a virtual network that corresponds to a physical network (cables, switches, routers, etc.) The main components of a VPC are the subnet, the route table, and the internet gateway. This is the list of objects that have to be dealt with:

In AWS, things are a bit more complicated. If you are a Windows admin, you are used to either just enabling DHCP in the network settings for your server or manually entering an IP address, and you are done. (I can't believe that I wrote an IPv6 tutorial almost 10 years ago and that I only just started to work with IPv6 recently.) If you think you only have to enable IPv6 for your EC2 instance, you will be surprised at how complicated it still is to assign an IPv6 address in AWS more than 20 years after the first IPv6 packets were wired through the internet.
