Hello Everyone:
I am the OP of this thread. At least in my case I can verify that there is nothing nefarious going on with 'hosts' file content. (Hi mertz_mhz, on your Mac OS > 10 this file might reside in /etc/hosts, such as it is in Unix / Linux).
I don't use a Mac, but I have multiple Windows and Linux machines (the latter for professional work use; I don't mean to imply I've been trying to make the IKMM suites work under Linux via a Wine hack or something) and none of them can ping IKMM's server from my home ISP as described in great detail earlier in this thread.
My point is that my problem does not appear to be specific to the particular (Windows 10) workstation on which my IKMM products and Product Manager is installed. Which is, of course, also consistent with the fact that the pings (from any of my machines) make it out of my geographic region (Los Angeles CA USA) just fine, but die at the exact same point somewhere in Canada before reaching IKMM's servers. I can't see how this has anything to do with my local machine which is experiencing the problem.
This issue is also way beyond the scope and ability of a regular (IKMM or ISP) end user to fix. It's not as if AT&T (in my case) is going to change at an international level the routes that their packets take from LA to the UK, just for me.
IMO this is a serious issue that someone high up in IKMM IT/IS department has to take up with their ISP.
Hi mertz_mhz, if I may ask, where are you located geographically (even just roughly?)
Thank you,
-Michael
