| # dns-zone-aware | ||
| Example zone aware DNS server for AWS | ||
| Example DNS resolver that does availability zone aware DNS lookup (in AWS EC2). | ||
|
|
||
| How it works: | ||
|
|
||
| 1. On startup, it finds the current physical zone of the machine this is running at (by querying `http://169.254.169.254/latest/meta-data/placement/availability-zone-id`) | ||
| 2. Starts a DNS resolver at given address | ||
| 3. On receiving DNS request | ||
| 1. Assume we got the request for *foo.com* and our current zone id is *use1-az4* | ||
| 2. It will do a lookup (using given resolver or by default AWS VPC default resolver) for *use1-az4.foo.com*, if success, returns the result | ||
| 3. If step 2 failed, it will do a lookup for *foo.com* and return the result | ||
|
|
||
| To test: | ||
|
|
||
| 1. Run the server | ||
|
|
||
| ``` | ||
