DoH/DoT

Hi, how do you use this with a DoH/DoT resolver ?

See the PR and the examples here #102 (review)

dnsx supports DoH (DNS over HTTPS) resolvers using the -r flag with HTTPS URLs:

DoH Examples:

# Cloudflare DoH
dnsx -l hosts.txt -r https://cloudflare-dns.com/dns-query

# Google DoH
dnsx -l hosts.txt -r https://dns.google/dns-query

# Quad9 DoH
dnsx -l hosts.txt -r https://dns.quad9.net/dns-query

Multiple DoH resolvers:

echo -e "https://cloudflare-dns.com/dns-query\nhttps://dns.google/dns-query" > doh-resolvers.txt
dnsx -l hosts.txt -r doh-resolvers.txt

Mixed DoH + Standard:

echo -e "8.8.8.8\nhttps://cloudflare-dns.com/dns-query" > mixed.txt
dnsx -l hosts.txt -r mixed.txt

DoT (DNS over TLS):
DoT support is more limited. You can try:

dnsx -l hosts.txt -r tls://dns.google:853

But DoH is the more reliably supported option.

Verify it's working:

echo "example.com" | dnsx -r https://cloudflare-dns.com/dns-query -resp -a

The format auto-detection happens based on whether the resolver string starts with https:// or tls://.
