Fios Issue #2: tracert on Windows

Odd behavior was observed on Windows using Fios.  When I ran 'tracert' in cmd on Windows 10, it showed only two hops.  But on Linux it showed all the hops.

See this on Windows:


On Linux:


In short, it's Verizon Fios interfering with ICMP as Windows using ICMP, but Linux is using UDP.  I also tried Ubuntu on Windows, but got the same results of two hops.  It seems only true Linux traceroute works properly with Fios.

Solutions


1. CountryTraceRoute -
http://www.snapfiles.com/get/ctraceroute.html
Simple application, not perfect, but seems to be ok.  Below screenshot is from the download site, but when it's ran, it shows same information as tracert for #1, #2 hops, but shows more afterward.



2. NMAP - https://nmap.org
This is the real replacement of tracert; it requires to install npcap.  (WinCap is no longer developed.)


Use:
nmap -sU --traceroute www.google.com

Windows MTR

Note that this is here fore reference.  Using 'mtr' did not fix the issue nor worked around the Fios issue.
