Query ‘Cloudflare’ Domain Name System (‘DNS’) Servers over ‘HTTPS’

Description

Domain Name System (‘DNS’) queries are generally perfomed by operating system calls when browsing the internet or making other network connectios. DNS over ‘HTTPS’ services offer more local confidentiality and some ‘DNS’ providers like Cloudflare offer (https://developers.cloudflare.com/1.1.1.1/dns-over-https/json-format/) an ‘API’-like service along with other privacy-enabled ‘DNS’ offerings. Tools are provided to query this ‘DNS’ ‘API’.

What’s Inside The Tin

The following functions are implemented:

• dig: Make a single DNS query (just an “alias” to query())
• query: Make a single DNS query
• nslookup: Make a single DNS query (just an “alias” to query())
• valid_dns_types: Valid DNS types

TODO

• batch_query() method
• as.data.frame() method
