Your IP – Now My IP

The Internet Protocol (IP) address is provided to each device connected to the network. IP addresses consist of four numbers and look like 117.0.0.1. All of these numbers are usually assigned to Internet Service Providers (ISPs) within blocks based on regions. An IP address can be used to identify the country or region from which a device connects to the Internet.

Previously, ISPs issued an IP address for each user. These are called static IP addresses. ISPs now dynamically issue IP addresses from a pool of addresses (using DHCP). These are known as dynamic IP addresses. With virtual hosting, a single machine can act as multiple machines (with multiple domain names and protocol addresses).

The IP address reveals your…

With an IP address, it is quite easy to identify the place, including the country, state and city, using some web applications. Find the IP address of email senders from Yahoo, Rediff, Hotmail, etc. It is easy. Google masks the outgoing IP address of the sender sending mail through the Gmail web interface.

Using the IP-Tracker software installed on remote devices, you can access it from anywhere. IP-Tracker constantly monitors the dynamic IP address of the device and every time the IP address changes, it sends an email to your inbox to notify you of your new IP address.

How can I change my IP address?

  • If you are using a dial-up connection, you can simply dial through an alternate access number
  • For cable/DSL with a router:
  1. Open the control panel of your router
  2. Increase your MAC address by one number
  3. Then disconnect and reconnect your router. Now after doing this, your ISP will give you a new IP.
  4. If you encounter any problem, go back to previous MAC

How can I hide my IP address?

You can hide your IP address using…

  • IP change software.
  • anonymous software

Advantages of knowing my IP address

Knowing your IP address may allow you to access

  • services running on your machine (for example, online games)
  • servers (FTP, web, mail)
  • remote access utilities (MS Remote Desktop, GoToMyPC, PCAnywhere).

Virtual Hosting Explained

Virtual hosting allows a single machine to act as multiple machines (with multiple domain names and IP addresses).

How can I find out the IP address of the person you have been chatting with on your IM (Instant Messenger)?

  • If you want to know the IP, run a packet sniffer and start a file transfer.
  • You’ll need to set up a file transfer to see the Internet Protocol address of the person you’re communicating with; the transfer will go virtually directly to the other person’s computer. Otherwise, get the protocol address of the server.

If you run a packet sniffer, you should send a request using ICMP then TCP with the SYN ACK flag set) and the destination computer will respond. The TCP SYN ACK packet gives you the destination device’s port number, IP address, etc.

But there are exceptions. If the target device is running behind a router with a hardware firewall, you may not get the actual protocol address you’re looking for; instead it will show a WAN IP of some sort, usually the ISP’s.

In conclusion, since Internet Protocol addresses reveal your physical location and also provide more details to others; it is recommended not to display your protocol address except for essential and important communications. Hide the IP address for your safety and that of your device.
