2. Basic Usage

Doggo simplifies the process of querying DNS records with straightforward commands. Here’s how to perform common DNS queries:

a. Querying DNS Records

To retrieve specific DNS records for a domain, use the following syntax:

doggo <domain> [record-type]

For example, to query the A record for example.com:

doggo example.com A

b. Query All Record Types

Retrieve all supported DNS record types in a single command using the --any flag:

doggo example.com --any

c. Reverse DNS Lookup

Perform a reverse DNS lookup to find the domain associated with an IP address:

doggo --reverse 8.8.8.8

d. Using DNSSEC

Enable DNSSEC validation to ensure the authenticity of DNS responses:

doggo example.com --dnssec

Note: DNSSEC validation requires the target domain to be properly signed with DNSSEC.

3. Using Secure Protocols

Doggo enhances DNS query security by supporting encrypted protocols. Here's how to use them:

a. DNS-over-TLS (DoT)

Encrypt DNS queries using TLS to protect against interception and tampering:

doggo example.com @tls://1.1.1.1

b. DNS-over-HTTPS (DoH)

Perform DNS queries over HTTPS for added privacy and compatibility with HTTPS infrastructure:

doggo example.com @https://dns.google

c. DNS-over-QUIC (DoQ)

Utilize the QUIC protocol to achieve enhanced security and improved performance:

doggo example.com @quic://1.1.1.1

These secure protocols ensure that your DNS queries remain private and are shielded from potential eavesdropping or manipulation.

4. Tweaking Query Behavior

Doggo provides various options to customize the behavior of DNS queries to suit specific needs:

a. Set Flags on Queries

Customize DNS query parameters using flags:

--aa: Request an Authoritative Answer.
--ad: Request Authenticated Data.
--cd: Disable Checking.
--rd: Recursion Desired (enabled by default).

Example of disabling checking:

doggo example.com --cd

b. Specify Resolver Timeout

Set a timeout duration for DNS queries to prevent hanging:

doggo example.com --timeout=5s

c. Control Nameservers

Specify which nameservers to use for DNS queries:

doggo example.com --nameserver=8.8.8.8

You can choose to use the system's /etc/resolv.conf or override it with user-specified nameservers as demonstrated above.

5. Advanced Features

Doggo offers a range of advanced features to enhance DNS querying and analysis:

a. Multiple Resolver Comparison

Compare DNS responses from different resolvers to assess performance and reliability:

doggo example.com @1.1.1.1 @8.8.8.8

b. Shell Completions

Enhance your command-line efficiency with auto-completions for zsh and fish shells:

doggo completion zsh > /path/to/zsh_completion

doggo completion fish > /path/to/fish_completion

c. Logging and Debugging

Enable debugging to troubleshoot DNS queries:

doggo example.com --debug

This will provide detailed logs of the DNS query process, aiding in identifying issues.

6. Resolver Strategies

Doggo allows users to define how nameservers are queried, offering flexibility in resolver selection:

Strategy	Description
`all`	Queries all available nameservers.
`random`	Queries a randomly selected nameserver.
`first`	Queries the first nameserver in the list.

To specify a resolver strategy, use the --strategy flag:

doggo example.com --strategy=all

Choosing the appropriate strategy helps in managing load and ensuring reliable DNS responses based on your requirements.

7. DNS Security Extensions (DNSSEC)

Doggo supports DNSSEC, which adds an authentication layer to DNS queries to verify the integrity and origin of DNS data:

Enable DNSSEC validation using the --dnssec flag:

doggo example.com --dnssec

DNSSEC helps prevent attacks like DNS spoofing by ensuring that the responses received are legitimate and have not been tampered with.
