Author:       Juen/Project R3D+Appendix+Nah-Kolor
Uploader:     biuro cdlabel info (Pawel Juen Nowak)
Type:         comm/tcp
Version:      1.1
Architecture: m68k-amigaos >= 2.0.0

 A lightweight DNS lookup utility for classic Amiga computers.

 REQUIREMENTS:

 - MC68000 or better
 - Kickstart 2.0 or higher
 - A TCP/IP stack with bsdsocket.library (AmiTCP, Roadshow, Miami, etc.)

 FEATURES:

 - DNS query via raw UDP packets (port 53)
 - A record (IPv4 address) lookup
 - CNAME (canonical name) lookup
 - MX (mail exchange) lookup
 - PTR (reverse DNS) lookup
 - Custom DNS server selection
 - Auto-detect DNS server from AmiTCP configuration
 - Fallback to 8.8.8.8 (Google DNS)
 - Full DNS packet building and parsing
 - DNS compression pointer handling
 - Pure MC68000 code - no 68020+ instructions

 USAGE:

 From CLI:

   AveHOST aminet.net              ; A record lookup
   AveHOST -t MX amiga.org         ; MX record lookup
   AveHOST -t PTR 8.8.8.8          ; reverse DNS
   AveHOST -s 1.1.1.1 google.com   ; use Cloudflare DNS

 OPTIONS:

   -t <type>     Record type: A, CNAME, MX, PTR (default: A)
   -s <server>   DNS server IP address
   -h            Show help

 NOTES:

 - Builds DNS packets from scratch (no resolver library).
 - Default DNS server read from AmiTCP:db/resolv.conf or
   ENV:resolv.conf. Falls back to 8.8.8.8 if not found.

 CHANGELOG:

 v1.1 (28.03.2026)
   - Fix: DNS response parsing bounds check prevents crash on malformed replies
