Proxy Bypass websites

[imiddleton25]

We have no link that the student would find to our routers in ipconfig .
We have a solid protected network where all the machines are on vlans gateways are set on the managed switches and then only the switch forward to the Internet filtering box which in turn goes out to the router. So no amount of playing on workstations will give them this information. I find it hard to believe that anyone would be connected directly to the router in a school environment anyway.

I am not sure what they thought of, so I brought it to attention. I know my school has not even changed the IP to something less common.

joe, hiding IPS as "something less common" is worthless. If you tried your tricks on *most* networks, and *all* properly configured networks, you'd fail.

@Joewalsh2008: Your administrator should really know better.

[joewalsh2008]

All I am saying is I typed in the address 192.168.0.1, it happens to be my routers IP. It also happens to be my schools IP. The IP is set the same for many routers. I have had 3 of them with the same IP and its not my computers IP that I am seeing. I am just saying that IPs on local networks are generally the same as a different locked network. Unless they have been changed. My school may not have thought of it because it is only High School. I was not sure how many places knew about the common IPs so, I brought it to this site to let you all check to see if yours was hidden better then mine.

It may save you from a smart student that wants to distrupt the internet. I do not know how to stop them but I will let you know what you need to try to prevent. Access to the schools routers and services. I can do it at my school and showed one of the computer teachers so that he could show the Admins. Type in the schools IP. Go to the command prompt and type in ipconfig/all, after you know the ip go to the internet address bar and type in the ip address, it will bypass the proxy you use since it goes to the router not the internet and it will let the person who goes there configure the internet rules to their liking and shut it down if they wish. Yes, students may not know the ip and can't use the command prompt, but I found ours by typing in mine. Routers have a preset local IP for access by a connected computer. Most routers have the same IP. If your in NC it is more then likely one of the following 192.168.0.1, 192.168.1.1, 192.168.2.1 those three ips will access most routers from a base computer connected to it. Check it out, your school or organization may have figured this out already but mine has not so I am bringing it to the attention of those it should concern.

This is rubbish and for the following reasons:

1. Access to the command prompt is restricted
2. Access to the internet directly is restricted, ALL internet traffic MUST originate from the content filter
3. ACLs on routers and switches provide a set route around the network
4. VLANs and seperate subnets prohibit direct access via this means anyway
5. I could go on but it would be along list....

The point I am making is do not underestimate those of us that have been doing this for years we have leanrt a thing or two

i really hope this comment is a joke !!!

I think you might be mistaking a home router for a commercial router. However, joewalsh2008, if the security is really that relaxed at your school then have fun I suppose.

Security through obscurity is no security at all. If your school administrators ect haven't secured this then they must be either incredibly stupid, or very trusting. Most routers have a password system included in there firmware anyway that should prevent most people meddling. As for blocking command prompt also make sure you cant do the same in notepad by saving it as a batch file.
