偶然发现个 DNS 诊断解析的工具 dnslookup，且在活跃更新维护中，跨平台
下载后可以不设置环境变量，直接丢进系统路径 %windir%，就能在终端里直接使用了
支持所有已知的 DNS 协议：普通 DNS、普通 DNS-over-TCP、DoH、DoT、DoQ、DNSCrypt

Plain DNS:
dnslookup example.org 94.140.14.14
Plain DNS-over-TCP:
dnslookup example.org tcp://94.140.14.14
DNS-over-TLS:
dnslookup example.org tls://dns.adguard-dns.com
DNS-over-TLS with IP:
dnslookup example.org tls://dns.adguard-dns.com 94.140.14.14
DNS-over-HTTPS with HTTP/2:
dnslookup example.org https://dns.adguard-dns.com/dns-query

DNS-over-HTTPS forcing HTTP/3 only:
Google DNS
dnslookup example.org h3://dns.google/dns-query
DNS-over-HTTPS with IP:
dnslookup example.org https://dns.adguard-dns.com/dns-query 94.140.14.14
DNS-over-HTTPS with basic auth (supported by AdGuard DNS):
dnslookup example.org https://username:password@d.adguard-dns.com/dns-query
DNSCrypt (stamp):
dnslookup example.org sdns://AQIAAAAAAAAAFDE3Ni4xMDMuMTMwLjEzMDo1NDQzINErR_JS3PLCu_iZEIbq95zkSV2LFsigxDIuUso_OQhzIjIuZG5zY3J5cHQuZGVmYXVsdC5uczEuYWRndWFyZC5jb20
DNSCrypt (parameters):
dnslookup example.org 176.103.130.130:5443 2.dnscrypt.default.ns1.adguard.com D12B:47F2:52DC:F2C2:BBF8:9910:86EA:F79C:E449:5D8B:16C8:A0C4:322E:52CA:3F39:0873
DNS-over-QUIC:
AdGuard DNS
dnslookup example.org quic://dns.adguard-dns.com
Quad9
dnslookup example.org quic://9.9.9.9
Sending a PTR query for an IPv4 address (IP address is recognized automatically when RRTYPE is not specified):
dnslookup 8.8.8.8
Sending a PTR query for an IPv6 address (IP address is recognized automatically when RRTYPE is not specified):
dnslookup 2606:4700:4700::1111
Machine-readable format:
JSON=1 dnslookup example.org 94.140.14.14
Disable certificates verification:
VERIFY=0 dnslookup example.org tls://127.0.0.1
Specify the type of resource record (default A):
RRTYPE=AAAA dnslookup example.org tls://127.0.0.1
RRTYPE=HTTPS dnslookup example.org tls://127.0.0.1
Specify the class of query (default IN):
CLASS=CH dnslookup example.org tls://127.0.0.1
Set DNSSEC DO bit in the request's OPT record:
DNSSEC=1 dnslookup example.org tls://8.8.8.8
Specify EDNS subnet:
SUBNET=1.2.3.4/24 dnslookup example.org tls://8.8.8.8
Add EDNS0 Padding:
PAD=1 dnslookup example.org tls://127.0.0.1
Specify EDNS option with code point code and optionally payload of value as a hexadecimal string: EDNSOPT=code:value. Example (equivalent of dnsmasq's --add-cpe-id=12345678):
EDNSOPT=65074:3132333435363738 RRTYPE=TXT dnslookup o-o.myaddr.l.google.com tls://8.8.8.8
Combine multiple options:
RRTYPE=TXT SUBNET=1.1.1.1/24 PAD=1 dnslookup o-o.myaddr.l.google.com tls://8.8.8.8
Verbose-level logging:
VERBOSE=1 dnslookup example.org tls://dns.adguard-dns.com
