When the transfer to Amazon Route 53 is complete, verify that the name server for your domain has indeed changed. On a Linux computer, use the dig DNS lookup utility. For example, use this dig command:.

Now, suppose you configure internal hostnames as CNAME targets in the external “example. Com” DNS servers, and then try to internally look up “myserver. The AWS resolver consults the global DNS hierarchy and ends up asking one of the authoritative name servers for “myserver. The AWS resolver realizes that it does not need to consult an external entity to answer this new question, because it is authoritative for the fake internal domain, simply responds with the correct answer, which it already knows. ” The response will essentially say “all I know is that to find myserver. Com, you should look up ip-1.

But how to get a static private IP address for a resolver EC2 instance running inside an AWS VPC. Our solution was to create an ENI (Elastic Network Interface) and “hard-code” a private IP address for it. You cannot use an EIP (Elastic IP) since EIPs are public, not private, IPs. If it were to change, numerous systems would break. Google uses the easy-to-remember “8. As mentioned earlier, we do not want to constantly change resolver IP addresses. 8” IPv4 address as a public resolver. For similar reasons, we want our internal resolvers to have static IP addresses.

Amazon provides a DNS server that resolves. In EC2-Classic, the Amazon DNS server is located at .

A central VPC can host shared services that all other VPC hosted systems can access. However, that is beyond our scope here and would require another blog post or two. We still need to solve for a situation where the Central VPC goes down. Not needing to deploy the same service into each VPC helps reduce costs.

If you want to access your servers by my-dns-name you’ll need to setup your own DNS server. By default AWS VPC handles DHCP for you and comes with Amazon’s DNS server.

When a VPC is created, it is given a default DNS server that all VPC EC2 instances will use to resolve names. However, if your AWS VPC is connected to your internal network and you expect EC2 instances to be able to resolve names of internal systems in your data center or office, then the default VPC resolver cannot help – it does not know the internal DNS and you cannot log in to it and configure it to do forwarding.

The Amazon EC2 Service Level Agreement commitment is 99. 95% availability for each Amazon EC2 Region. The service runs within Amazon’s proven network infrastructure and data centers. Amazon EC2 offers a highly reliable environment where replacement instances can be rapidly and predictably commissioned.

When queried from inside your EC2 deployment, the result will be the internal IP address via some DNS magic that EC2 does transparently. Or from outside, it will return the external public IP address. Com using that hostname as the CNAME target will do the same thing. Conversely, if you have a machine with a public IP and a corresponding public hostname, like ec2-x-x-x-x.

    Did you create this zip file on a Linux system or in Windows. A few questions for you. I have seen it happen that if you create the file using WinZIP, for some strang reason the archive will show up as incomplete when you try to extract it on Linux or Mac OS X. If you created the ZIP file in Windows using WinZIP, try to open it in Windows with WinZIP and see if you can at least see a list of files contained within the archive. If you can, extract the files on Windows and use a real archive tool like 7 Zip or WinRAR to re-create the archive again.
