    I want to apologize about the broken blurs in the video. Premiere was giving me a fit and I didn’t realize until I sat and watched the rendered video.
    I do plan to shorten videos where I can and work on learning editing software that doesn’t behave poorly.

    I'm on the same ISP and I had wondered the same things. Would love to see/discuss more. Great content.

      Oh that's cool! Is your first hop also a Juniper? I believe they use MX as their edge routers.

      @@LANRanger Not sure yet. My link has had some signal power level issues and I'm waiting on them to replace what I assume is the SFP transceiver in the cabinet to get the signal to me. I've been deep diving FTTH and direct fiber connections and came across your super relevant video. Our ONTs are Mikrotik so I've been digging around there until my connection gets fixed and was led to some of the same concerns you have shown.

      @@LANRanger They got my connection back up today. Looks like I'm on CGNat so can't replicate your experience. First hop out is a Juniper though. Im going to request a static and see what I can find then.

    My ISP can do this as well, They switched to having CGNAT a few years ago but thankfully I already had a static, but I also have a 2nd seperated network using a static thats with other account thats in another town, and it works perfectly fine. Along with ZERO ACL config. I can see modems from 2,000 miles away, APC boxes, QAM boxes, Fiber switches, switches, and so on.. Of course thankfully most of the important stuff is behind a password, which I'd hope is not default. Been like this the past 15+ years.
    Up until a few years ago the modems/gateways you could login to them with the default login so one could change someones WiFi settings, open ports, even down to seeing numbers that where called if there modem had a built in ATA. It not limited to the headend. Someone in California for example could see someones modem on the same ISP in Tennessee. Can still see modems, but thankfully one cannot login to it unless they know the password set on the actual gateway other than just seeing signal levels etc.
    Not sure why my previous comment was removed.

      @@HPad2 hey thanks for the comment! Interesting stuff for sure.
      I did not see your previous comment. So I’m unsure about that, could possibly be UA-cam’s algorithm?
      Anyway, that’s amazing info.

      @@LANRanger I think the comment was removed as my first post had private space IPs and maybe they thought it was spam. I removed that part of my comment and it seemed to had not disappeared that time.

    Was holding my breath until you said you live in Alabama lol. I work for a major ISP and know decently well how our network is set up, and I've theorized about things like this before. Thankfully, we don't have service in Alabama so it's not my problem... yet.
