🩹 [Patch]: Enrich the output from Resolve-DnsHost to match Windows' Resolve-DnsName

[Copilot]

This patch enriches the output from Resolve-DnsHost to provide detailed DNS record information similar to Windows' Resolve-DnsName cmdlet.

Changes Made

New DnsRecord Class

Added a new DnsRecord class with properties that match the structure of Resolve-DnsName output:

• Name, Type, TTL, Section, IPAddress, Address, QueryType
• IP4Address/IP6Address (populated based on record type)
• CharacterSet, DataLength

Enhanced Resolve-DnsHost Function

Updated the function to:

• Return an array of DnsRecord objects instead of a single DnsHost object
• Create separate records for each resolved IP address
• Automatically identify A vs AAAA record types based on address family
• Include rich DNS metadata for each record

Before vs After

Before (simple output):

Name: hostname
Alias: alias  
AddressList: [array of IPs]

After (rich output matching Resolve-DnsName):

Name         : localhost
Type         : A
TTL          : 60
Section      : Answer
IPAddress    : 127.0.0.1
Address      : 127.0.0.1
QueryType    : A
IP4Address   : 127.0.0.1
IP6Address   : 
CharacterSet : Unicode
DataLength   : 4

The output now provides the same rich DNS record information as Windows' Resolve-DnsName, including proper handling of both IPv4 (A records) and IPv6 (AAAA records) with appropriate metadata.

Fixes #4.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• 8.8.8.8.in-addr.arpa
  • Triggering command: pwsh -Command try { [System.Net.Dns]::GetHostEntry('8.8.8.8') | Format-List } catch { Write-Host 'Error:' $_.Exception.Message } (dns block)
• google.com
  • Triggering command: pwsh -Command . ./src/classes/public/DnsHost.ps1; . ./src/functions/public/Resolve-DnsHost.ps1; Resolve-DnsHost -Name 'google.com' (dns block)
  • Triggering command: pwsh -Command . ./src/classes/public/DnsHost.ps1; . ./src/functions/public/Resolve-DnsHost.ps1; $result = Resolve-DnsHost -Name 'google.com'; $result | Format-List (dns block)
  • Triggering command: pwsh -Command . ./src/classes/public/DnsHost.ps1; . ./src/functions/public/Resolve-DnsHost.ps1; $result = Resolve-DnsHost -Name 'google.com'; Write-Host 'Result:'; $result (dns block)
• nonexistent.invalid.domain.test
  • Triggering command: pwsh -Command . ./src/classes/public/DnsRecord.ps1; . ./src/functions/public/Resolve-DnsHost.ps1; Import-Module Pester -Force; Invoke-Pester tests/Dns.Tests.ps1 -Output Detailed (dns block)
  • Triggering command: pwsh -Command . ./src/classes/public/DnsRecord.ps1; . ./src/functions/public/Resolve-DnsHost.ps1; Import-Module Pester -Force; Invoke-Pester tests/Dns.Tests.ps1 -Output Normal (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
