dnc (Domain Name Checker), is a CLI tool to check domain names configuration.
dnc requires Python 3.5+ and the following Python modules:
- Dnspython
- PrettyTable
- pyOpenSSL
dnc [-46hmnsv] domain
The options are as follows:
-4 Resolve and display A records (IPv4 addresses).
-6 Resolve and display AAAA records (IPv6 addresses).
-h Display usage.
-m Resolve and display MX records (Mail Exchange).
-n Resolve and display NS records (Name Servers).
-s Display SSL/TLS certificate expiration date.
-v Display version.
Here is the output of running dnc querying NS and A records, along with SSL certificate expiration date for two domains:
$ dnc -n4s cambus.net toolchains.net
