Solution

dog — DNS lookup utility. It has colorful output, supports DNS-over-TLS and DNS-over-HTTPS protocols, and can emit JSON. More information: <https://github.com/ogham/dog#examples>.

Lookup the IP(s) associated with a hostname (A records):

dog {{example.com}}

Query the MX records type associated with a given domain name:

dog {{example.com}} MX

Specify a specific DNS server to query (e.g. Cloudflare):

dog {{example.com}} MX @{{1.1.1.1}}

Query over TCP rather than UDP:

dog {{example.com}} MX @{{1.1.1.1}} {{[-T|--tcp]}}

Query the MX records type associated with a given domain name over TCP using explicit arguments:

dog {{[-q|--query]}} {{example.com}} {{[-t|--type]}} MX {{[-n|--nameserver]}} {{1.1.1.1}} {{[-T|--tcp]}}

Lookup the IP(s) associated with a hostname (A records) using DNS over HTTPS (DoH):

dog {{example.com}} {{[-H|--https]}} @{{https://cloudflare-dns.com/dns-query}}
