dnslookup example.org 94.140.14.14
```
Plain DNS-over-TCP:
```shell
dnslookup example.org tcp://94.140.14.14
```
DNS-over-TLS:
```shell
dnslookup example.org tls://dns.adguard.com

DNS-over-TLS with IP:
```shell
dnslookup example.org tls://dns.adguard.com 94.140.14.14
```
DNS-over-HTTPS with HTTP/2:
```shell
dnslookup example.org https://dns.adguard.com/dns-query
```
DNS-over-HTTPS with HTTP/3 support (the version is chosen automatically):
```shell

```
DNS-over-HTTPS forcing HTTP/3 only:
```shell
dnslookup example.org h3://dns.google/dns-query
```

```
DNS-over-HTTPS with basic auth (supported
by [AdGuard DNS](https://adguard-dns.io/)):
```shell
dnslookup example.org https://username:[email protected]/dns-query
```
DNSCrypt (stamp):
```shell
dnslookup example.org sdns://AQIAAAAAAAAAFDE3Ni4xMDMuMTMwLjEzMDo1NDQzINErR_JS3PLCu_iZEIbq95zkSV2LFsigxDIuUso_OQhzIjIuZG5zY3J5cHQuZGVmYXVsdC5uczEuYWRndWFyZC5jb20
```
DNSCrypt (parameters):
```shell
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:
```shell
dnslookup example.org quic://dns.adguard.com
```
Sending a PTR query for an IPv4 address (IP address is recognized automatically
when RRTYPE is not specified):
```shell
dnslookup 8.8.8.8
```
Sending a PTR query for an IPv6 address (IP address is recognized automatically
when RRTYPE is not specified):
```shell
dnslookup 2606:4700:4700::1111
```
Machine-readable format:
```shell
JSON=1 dnslookup example.org 94.140.14.14
```
Disable certificates verification:
```shell
VERIFY=0 dnslookup example.org tls://127.0.0.1
```
Specify the type of resource record (default A):
```shell
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):
```shell
CLASS=CH dnslookup example.org tls://127.0.0.1
```
Set DNSSEC DO bit in the request's OPT record:
```shell
DNSSEC=1 dnslookup example.org tls://8.8.8.8
```
Specify EDNS subnet:
```shell
SUBNET=1.2.3.4/24 dnslookup example.org tls://8.8.8.8
```
Add EDNS0 Padding:
```shell
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`):
```shell
EDNSOPT=65074:3132333435363738 RRTYPE=TXT dnslookup o-o.myaddr.l.google.com tls://8.8.8.8
```
Combine multiple options:
```shell
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:
```shell
VERBOSE=1 dnslookup example.org tls://dns.adguard.com
