- Update to version 2.9.3
Bug Fixes
* TCP Traceroute Fixed: The most important fix in this release
resolves a regression where dnstraceroute with TCP protocol
(-T flag) would immediately fail with "No route to host" errors
During TCP traceroute operations, intermediate hosts send ICMP
Time Exceeded messages when TTL expires, which the TCP stack
interprets as EHOSTUNREACH errors. These errors were being
unconditionally re-raised even in traceroute mode where they're
expected behavior. The fix now properly handles these errors
during traceroute, allowing TCP path discovery to work as
intended.
* QUIC and HTTP/3 Traceroute TTL Control: Previously,
dnstraceroute couldn't control TTL values when using QUIC (-Q)
or HTTP/3 (-3) protocols, basically breaking traceroute
functionality for DoH3 and DoQ. The fix enables proper TTL
manipulation for both protocols, allowing users to trace
network paths to DNS-over-QUIC and DNS-over-HTTP/3 resolvers.
* Timing Accuracy Improvements: Replaced dnspython library
internal timing with Python's perf_counter for response time
measurements across all DNS protocols. This provides more
accurate and consistent latency measurements.
* Better Error Handling for Modern Protocols: Improved error
handling for DoH, DoH3, and DoQ protocols to display
user-friendly error messages instead of Python stack traces.
Connection refused errors are now treated as transient across
all DNS protocols, and transient QUIC connection failures
(UnexpectedEOF exceptions) are handled gracefully, allowing
dnsping to continue with the next attempt.
* DNSSEC Information Display: Added explanation of DNSSEC flags
and Extended DNS Error (EDE) codes in dnsping output. When
DNSSEC validation is enabled, users now see detailed
explanations of response codes like "DNSSEC Bogus" with
human-readable descriptions of what went wrong, making DNSSEC
troubleshooting easier.
* Command-Line Parameter Validation: Added mutual exclusivity
validation to command-line parameters across all tools.
Conflicting protocol flags (like -T and -H used together) now
trigger clear error messages instead of unpredictable behavior,
preventing user confusion and potential misdiagnosis of DNS
issues.

- Update to version 2.9.2
Bug Fixes
* Network Resilience: dnsping now survives transient network
errors instead of exiting fatally. When WiFi is toggled,
network cable is unplugged, or the system sleeps/resumes,
dnsping prints the error message and continues with the next
ping attempt, behaving like traditional ping. The fix also
improves error handling and makes it platform-portable.
* Answer Display: The -a flag in dnsping now displays the first
answer from the response regardless of record type, with the
type prepended for clarity
(e.g., [RDATA: CNAME res130.qams5.on.quad9.net.] or
[RDATA: A 142.250.179.174]). Previously it filtered by the
requested type only, which meant CNAME responses were silently
ignored.
* JSONL Output: The -j flag in dnseval now outputs valid JSONL
format with one JSON object per line, instead of
concatenating JSON objects back-to-back. The old format was
not parse-able by standard JSON parsers. Each line can now be
independently parsed with tools like jq.
* NSID Option Consistency: Fixed NSID EDNS option in dnsping to
use bytes instead of string for consistency with the rest of
the codebase and correct wire format.
* Exit Code Handling: All tools now return exit code 0 when
invoked with the --help flag, following standard conventions.
* Race Condition Fix: Fixed a time-of-check to time-of-use race
condition in dnsping that could cause negative sleep duration
in the interruptible sleep loop.

Fri Oct 31 10:49:42 UTC 2025 - Martin Hauke <mardnh@gmx.de>
- Update to version 2.9.1
* Multithreaded DNS Evaluation: dnseval now uses concurrent
evaluation when testing multiple DNS resolvers, improving
evaluation times. The tool employs ThreadPoolExecutor with up
to 10 worker threads for parallel testing while maintaining
thread-safe output handling. Results continue to be displayed
in the same order as the input file.
* Cookie Display Enhancement: DNS COOKIE output in dnsping is
now truncated to 8 hex characters followed by "..." in normal
mode, keeping output compact and readable. Full cookie details
remain available when using verbose mode.

results while preserving full text in verbose mode.
