Computer receiving incorrect IPV4 addresses

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.

Running tracerts just results in me getting timeouts on those requests.

The last hop will be always be a timeout since ping does not work. What you are attempting to determine with traceroute is how far from you the blockage is. Each line in the trace is router in the path. Most times the first one is a router in someone house but in your case it will be the college router. You should at least see that one.

I am beginning to suspect the college has some form of security blocking you. Many time they require you to log into some system to gain access. You may be best off calling the IT at the college and see if they can be of assistance.

I'm not sure how to answer this. The tracert appears to do three hops I think before it says timeout, I'm not sure if that's correct.

I have contacted the IT company and they're currently being very slow about fixing this issue.

The last IP you see is device you would need to get access to so you could determine why the device one hop further is not responding. Really all you can do is give the traceroute results to the IT department to help them since they should be able to get into that equipment.

It is actually typical for a router to have dns/default gateway as 10.0.1.1 assuming your IP address is something along the lines of 10.0.1.x (value of x being anything between 2 to 254).
So if your network information looks something like this:

IP Address: 10.0.1.x (again wight he value of x being a number between 2 to 254)
sunbet mask 255.255.255.0
default gateway: 10.0.1.1

If you are concerned with the DNS/DHCP being same as your default gateway. This is nothing to worry about, Basically the default gateway is the IP address of your router. The router also has a built in DHCP server (this your default gateway is same as DHCP server), and similarly with DNS server.

PS: On a side note if you this is because you were expecting 192.168.x.x and it is not. There are 3 segments reserved for private addresses (aka home use). These are: 192.168.x.x 172.(16-32).x.x and 10.x.x.x (again in this case the value of x can be between 0 and 255).
