DNS Server issue

[Sparseic]

So I've been having this issue (see attachment below) for a long time now, this started when I bought a new PC and until then I have never found a solution to fix it. I have already tried following tutorials on youtube and searching for solutions on google, not a single one worked for me.

 

I currently have a CAT6E Ethernet Cable that supports gigabit, this is the same cable I used in my old PC that didn't have the issue before. Although I did reconnect it to my old PC again a few days ago, to my surprise the same issue has also started to appear too.

 

Some of the solutions I have already tried;

 

- Using different DNS servers such as 8.8.8.8 or 1.1.1.1, tried restarting after each one also and nothing changed (My DNS servers for Ipv4 were already set to automatic before I changed this).

- Doing /ipconfig flushdns/registerdns/release/renew, restarted also after it, nothing changed.

- Doing /netish int ip reset / winsock reset

- Troubleshooting

* show your IP/DNS configuration,

* show ipconfig /all output

* show ping 1.1.1.1 and ping 8.8.8.8 output

8.8.8.8 and 1.1.1.1 ping result

 

 

I'm not sure how to show the DNS configuration, do you mean this?

 

Apologies about this, but I'm not sure if it's safe to show the results of my ipconfig to the internet (Not entirely sure which is safe to show and not safe to show)

my IP configuration, that shows information, that is important to connectivity:

IPv4 Address. . . . . . . . . . . : 192.168.0.200(Preferred)

Subnet Mask . . . . . . . . . . . : 255.255.255.0

Default Gateway . . . . . . . . . : 192.168.0.1

DNS Servers . . . . . . . . . . . : 192.168.0.50

                                              1.1.1.1

IPv4 Address is the same
Subnet Mask is the same

Default Gateway - 192.168.1.1

DNS Servers - 192.168.1.1 (and a bunch of like 2001:4450, etc)

1. What is the ethernet cable connected to upstream? Gateway, modem, router, switch? What are the makes/models of these hardware?
2. Try restarting the router/switch.
3. Please show us the CMD output for ipconfig /all. Obfuscate the IPv6 information.
4. Try disabling IPv6 under the NIC’s properties.

It is fine if your router works as DNS server properly — you can test it, if you login in router web interface and find something like Tools, and there Ping, and try to do some router DNS configuration test — ping <www.google.com> for example

 

And

you use where?

 

If your DNS server is your router, then these addresses you must use in router (other option is your ISP given DNS server).

I tried using them here:

1. It's directly connected to my router, the model is a HG6245D

2. Already tried that, still nothing.

3. Still a bit concerned due to privacy stuff, will the IPv6 the only thing I need to hide or are there more?

4. You mean here? If so I've already done it.

@Sparseic Try bypassing Window's IP stack with the following:

1. Open CMD
2. Enter nslookup and hit enter
3. Enter the following in order and record the output

dns.google
one.one.one.one

server 8.8.8.8
dns.google
one.one.one.one

server 1.1.1.1
dns.google
one.one.one.one

This will give you a better idea of where the root cause may lie. At first it defaults to the DNS server(s) provided by DHCP so this will test request to your router. From there you are querying defined servers and looking for a response.
