DNS lookups with dig

SLICC's built-in dig resolves DNS records over DNS-over-HTTPS (DoH):

dig <name> [type] [@server] [+opts] [--json]
dig <type> <name> [@server] [+opts] [--json]
dig -x <address> [@server] [+opts] [--json]
dig -v | dig --version

The name and supported record type may appear in either order. A lone positional is always the name and defaults to type A. Supported types are A, AAAA, MX, TXT, CNAME, NS, SOA, SRV, PTR, and CAA.

Resolver selection

Resolver	Supported @server values
Cloudflare	@1.1.1.1, @1.0.0.1, @cloudflare-dns.com
Google	@8.8.8.8, @8.8.4.4, @dns.google
Quad9	@9.9.9.9, @149.112.112.112, @dns.quad9.net

Cloudflare is the default. Any other @server falls back to Cloudflare and prints a note on stderr because arbitrary DNS servers cannot be queried over the built-in DoH transport.

Flags and output

• -x <address> performs an IPv4 or IPv6 reverse lookup as a PTR query.
• -v and --version print DiG 9.20.0-slicc (DNS-over-HTTPS) and exit.
• +short prints one answer value per line; --json prints the resolver response as JSON. They are mutually exclusive.
• Other +opts, such as +noall and +answer, are accepted as no-ops.
