Luzifer / dns_check
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 file.
Usage
# ./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
# ./dns_check -a "188.40.126.69" A luzifer.io
