dog

DNS lookup utility.

It has colorful output, supports DNS-over-TLS and DNS-over-HTTPS protocols, and can emit JSON.

• 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} --tcp

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

dog --query {example.com} --type MX --nameserver {1.1.1.1} --tcp

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

dog {example.com} --https @{https://cloudflare-dns.com/dns-query}
