When I plug in my ethernet cable into my PC, I get perfectly fine IPV6 connectivity, but I am told that I am not connected through IPV4. When I look into the details of the connection, I am shown that my IPV4 Default Gateway, DHCP Server and DNS server are all 10.0.1.1. Now I know that is definitely not what I should be getting for those values (At least I think so), however I'm unsure of how to make my PC do something different to this, and it's a problem that affects my laptop as well. Both of these devices could use a wired connection before I moved into University accommodation, and I do not know how to proceed with this problem.

Any thoughts?

Why would you think 10.0.1.1 is not a valid address. Seeing it assigned as DHCP server,gateway, DNS server is a pretty standard things if it is a router giving out the IP addresses.

If you can see the DHCP server set there must be a IPv4 ip address assigned to your ethernet nic. You should not have to do anything the DHCP server should give you proper addresses.

You should be able to ping 10.0.1.1

You machine may be confused and prefering the IPv6 ip address. You could try to disable the IPv6 in the network settings as see if the IPv4 works. IPv6 has very limited usefulness, there are not a lot of ISP or servers on the internet that support it.

The 10.0.1.1 is likely the IP address for the LAN side of your router/modem. The address is fine, since the router acts as your gateway and DHCP server, and forwards DNS requests to your ISP's DNS server.

If you are getting a good connection using IPv6, then you shouldn't worry about it.

Disabling IPV6 does nothing to help the situation.

I am able to ping 10.0.1.1

What happens if you run tracert to 8.8.8.8 or 4.2.2.2. This assumes you have direct internet access and do not have to use a proxy or other method to open a connection to the internet. Colleges many times have unusual security setups.
