    New ISP Help

    Help, I just switched ISPís and now I donít seem to be able to use any DNS servers other than the ones the new ISP provides and I also noted that when I run https://www.whatismyip.com/ I get a different address than what is shown in my router settings. I am using the ISPís cable modem that I have set to bridge mode. When I run whatismyip I get 189.4.xx.xxx but when I view my routers wan status page I see 100.6x.xx.x as my ip address.

    I am in Brazil and my former ISP was the local telecom using ADSL, now I am using the local cable company and they are providing the combination modem, router, WiFi and phone device. I wanted to use my own router so I set the device to bridge mode.

    Can anyone help me understand what might be causing me to get different IP address and what might be blocking my ability to change DNS servers?

    If you need more information please let me know.
    Thanks

    PS. I am not using a proxy server.

    Your ISP may be forcing some type of transparent proxy server on your connection to reduce their bandwidth loads. See what the hostname of those IPs is. Run traceroutes, to see what nodes are on the path between you and websites.

    There are other online services that can check your IP and proxy settings, what IP does the SG TCP Analyzer show? https://www.speedguide.net/analyzer.php
    What happens if you configure a third party DNS server?

    Thanks Philip, looks like my ISP is putting me behind a proxy server, if I attempt to use any other DNS servers websites will not resolve. My address is different based on what I see in my routers setting and what I see when I run the Analyzer. Not much I can do, just have to put up with it or find another ISP that can provide the speed I want.
    Thanks again.
