cURL: Selecting a custom DNS server to resolve domain names
#!/usr/bin/env bash
# this can be useful when developing against a custom DNS server, or
# for example, if you made a change to the DNS settings of a domain, and you
# know the authoritative nameserver IP address for a domain, you could use this
# to bypass the intermediate DNS cache, and apply an HTTP request using the new
# DNS settings supplied by your specified (authoritative) nameserver
curl --dns-servers <dns.ip,dns.ip> url.com
# acquire the nameserver using
dig url.com NS
# then ping the NS to get its IP address
