Laptop connected with limited access?
First off, I love your user name. Secondly, it sounds like your laptop wasn't able to get an IP address from your router. This is easy enough to fix. 1. Hold down the shift key, and right click on your desktop. 2. Select the option "Open Command Window Here". 3. Once the window opens (it should be a black screen with white lettering) type in "ipconfig /renew" and press the "Enter" key. This will force the computer to talk to the router and ask for a new IP address. If you're within range, you should get an IP address. I haven't heard of an issue like this that was Vista related. This is fairly common if you connect and disconnect from a wireless network a lot with a laptop.
What can I do if my IP address is hacked and used for illegal activities?
Valdislav is not necessary correct in disconnecting/reconnecting gets you a new IP address. IP addresses generally have a lease time assigned (anywhere from 8 hours to 72 hours), which means disconnecting and reconnecting gets you the same IP address unless your lease time has expired. If you believe your IP address may have been compromised you should immediately contact your Internet Service provider and tell them the time, date and reason why you think it has been compromised. However, because of the lease time, it may not be you who was causing the problems. If your provider sets your lease to 30 days (the industry standard for end users in big ISPs) and someone was using that IP address up until yesterday to post illegal content, then you get that IP address assigned to you today, you look like the bad guy to the website. To give you an example: You are currently using address 10.10.10.50. Bad guy A uses ip address 10.10.10.10 (yes, it's an internal, not an internet address but I'm just using it for simplicity) to post illegal content to Website A. The website notices and bans 10.10.10.10. The bad guy's lease on 10.10.10.10 runs out on Friday. Friday night your lease on 10.10.10.50 runs out and you are assigned 10.10.10.10, the IP that the bad guy was using. You visit website A, they see that the IP address was banned and throws up a bunch of big red warning boxes saying you're a horrible hacker. It actually means the IP address was used for hacking, not neccessarily Again though, if you are in any way concerned contact your ISP immediately with the time, date and reason. It's the best way to cover your butt and keep you out of any possible trouble. If you have any further questions please don't hesitate to let me know.
When we connect to VPN, does my internet usage increase more than normal?
In most VPNs, what happens is, your original IP packet is encapsulated inside another IP packet (in case of VPNs operating at layer 3 OSI) which is sent to the VPN server. The VPN server takes out the original packet from your VPN packet and does normal forwarding of it.So Yes,for the same amount of data services used, the data usage of your internet increases!VPNs are:*Slow*Use more data*MTU or MSS is decreased due to additional encapsulation*Most often Encrypted*VPN connection itself is detectable but not the actual data which is travelling in its tunnel.
My college WiFi has certain restrictions. One cannot download or surf more than 1.5 GB data per month. This is a very low limit. Is there any way to bypass such restrictions?
Thanks for A2A Yeah I agree with you , 1.5GB is very less that too for 1 month for an engineering student ohh !! so pity. We have 2GB for a day.Coming to your problem , Is there a portal in your college for authentication process or logging into your account ?? Is that a SSL secured one ?? I mean is it having https or http ?? If at all it's an http one u can easily hack ur friend's username password , use wireshark on any Linux machine , capture the packets , the http packets would be in a plain text !! obviously in a big college ppl logout login many times while your capture. So 30 days 30 accounts !! . After getting the password don't just straight away login , change your MAC so if at all anybody complains the admin can't find you. If at all he finds your MAC , he can't trace you with vendor name , he should go to that vendor and ask who bought mobile/laptop with that MAC address , which only cyber police can do , normal college's IT team would'nt go that far . If your portal is HTTPS secured , u have to do ARP spoofing on the entire network, so all packets would go through your device, where u can do SSL STRIP at your Linux machine(backtrack or Kali). But the admin definitely find heavy traffic going through ur MAC , would definitely take a action on you. So best alternative is create a fake access point , obviously who would leave open WiFi connection ??? all users will be connected automatically, so whatever traffic they surf portal , Gmail, fb , what not all SSL ones normal ones all!!! can be SSL stripped at your machine . Not only portal all passwords in your hand !! . At last , if you know which OS runs at the server you can do some statistical attacks, depending on the OS running , you can edit your data limit by yourself, but that requires good hacking skills. Above, ones are better for a noob.If nothing works use VPN.PS: search for how to you use wire shark, how to do Man in the Middle attack. ( quite easy ones) use macchanger every time. If you want data for tech purpose go on.. Don't waste ur time
What happens when you get IP banned over a VPN?
If you use a VPN and do bad stuff that gets a website to ban your IP, they will be banning the IP of the VPN service.If your VPN service assigns a static IP to each client, that would be you would be banned. If the VPN service dynamically assigns IP addresses (I think this is most likely), that would mean you could avoid the ban but reconnecting until you got a different IP from the VPN service. It would also mean other clients of that VPN service (when they got that IP assigned) would be banned from that site.Assuming you are not planning to do “bad stuff” (things leading to an IP ban) then I’d advise you find a cheap VPS service, install VPN software there, and then you’ll have a static IP address that is yours and yours alone.
