Hi. How can I check that the DNS I am using is valid, and not a bogus one as the result of some kind of malware? I used the "DNS LeakTest" website, and this gave 184.108.40.206 with the hostname 220.127.116.11.dyn.plus.net. The "F-Secure Router checker" says the same address. However, when I look in my router's setup pages, it gives a primary DNS of 18.104.22.168, and a Secondary DNS of 22.214.171.124. It is also set to "Auto". (My router is the one by SagamCom). If I change it from auto to manual, I can type new addresses into the boxes (but I didn't). I have heard that it's possible for DNS's to get changed so you get sent to fake sites, so I'm a bit concerned about this. Recently, emails from ASDA no longer display their logo, not even on older ones that did before. However, when I log in, everything seems normal, including lists of previous orders, contact details etc, and the site has the HTTPS padlock, so I guess it's not fake, but how could I be sure, and how can I correct it if it's wrong, and protect myself from the DNS getting hacked. What are Plusnet's official DNS server addresses. I can't find them on their website. I have looked at the "routersecurity.org" website, but they give a lot of info but now anything to tell me how to make sure I am safe (as far as DNS is concerned anyway). I'm not getting a lot of advertising or anything like that.
