dns\_check is a small utility to check major DNS services for records of a FQDN without having to query them one-by-one.
|
|
|
|
|
|
|
|
|
|
Use cases:
|
|
|
|
|
|
|
|
|
|
- Check whether the IP of your domain is consistent on all services
|
|
|
|
|
- Check whether your DNS change is already live for users of those services
|
|
|
|
|
- Have an automated check which tells you when something is not right
|
|
|
|
|
|
|
|
|
|
You can see the current table of nameservers oncluded on the build by browsing the [nameservers.yaml](nameservers.yaml) file.

|
## Usage
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
# ./dns_check --help
|
|
|
|
|
Usage of ./dns_check:
|
|
|
|
|
-a, --assert=[]: Exit with exit code 2 when these DNS entries were not found
|
|
|
|
|
--assert-threshold=100: If used with -a fail when not at least N percent of the nameservers had the expected result
|
|
|
|
|
-f, --full-scan[=false]: Scan all nameservers included in this build
|
|
|
|
|
-q, --quiet[=false]: Do not communicate by text, use only exit codes
|
|
|
|
|
-s, --short[=true]: Use short notation (only when using assertion)
|
|
|
|
|
--version[=false]: Print version and exit
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Use case: I know the IP of my domain and want to check whether all services report that IP

|
|
|
