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
