mturoute - Debug the MTU values between you and a host.
mturoute is a small command line application that uses ICMP pings of various sizes in order to determine the MTU values on the path between itself and the target system. It also includes a "traceroute" like mode where it will attempt to determine the lowest MTU between the local host and each hop in the communication.
There is my fork with many fixes of utility from here.The changes:
2026-03-15:* Built in the latest MSVC 18.4.0.
* Update Readme.
2026-03-06:
* Version 3.2.
* Improve compilation settings, memory usage and compatibility with older systems.
! Fixed a warning.
* Built in the latest MSVC 18.3.2.
* Reduced size (14'848 bytes -> 13'824).
2024-12-26:
* Version 3.1.
* Support from Windows NT 4.0 and above (built in the latest MSVC 18.1.1).
* Use of the latest available C standard.
* Compile with no additional instruction to improve compatibility with older machines (the 686 instruction set).
! Fixes additional memory alignment and incorrect type usage: a new warning from the compiler and a new PVS check. I'm exhausted of C code; it's very creepy.
* Reduced size (18'432 -> 14'848 bytes).
2024-11-25:
* Version 3.0.
* Support only from Windows XP and above (compiler reason, Build in the latest MSVC 17).
* Open Winsock in the final 2.2 mode (already supported in all NT versions).
* Fully reviewed and cleaned code:
! Fixes many logical errors in code.
! Fixes many critical language errors, like memory corruption, buffer overflows and other things.
like incorrect memory alignment, incorrect type usage e t.c.
! Correct usage of Windows API.
! Big improvements in speed.
* Big improvements in the text formatting and rewrite output.
* Significantly reduced size (62'464 -> 18'432 bytes).
* Enable -d (debug) and incomplete IPv6 test code only for debug build.
