Internet censorship puts restrictions on what information can be publicized or viewed on the Internet. Governments and other organizations commonly use internet censorship to block access to copyrighted information as well as to harmful or sensitive content. However, internet censorship can also be used as a propaganda method to promote specific religions and political agendas.

Domain Name Service (DNS) is a mapping of a domain name to an IP address, so that humans can remember computer address by a domain name instead of IP address. A DNS service is requested automatically when someone enters an web address on the web browser, so that the server knows how to find a website. When a user connects to the internet via a home router, the router gets an IP address and DNS server IP addresses via the DHCP it's Internet Service Provider (ISP). You may choose to use public DNS servers instead of the ones provided by your ISP by configuring your Internet connection manually.

To trace an email, you'll need to locate an email header that came with the email. Every email has email header and message body. An email may be going through a number of hops, and a header is appended with the IP address of the email server processing the email. When an email reaches the final destination, your email provider appends it's IP address to the header. The IP address of the very first header added to the email is the IP address of the sender's mail server.

A VPN, or Virtual Private Network, is used to securely connect to another network via a public or a private network. A VPN creates a private network within a broader network, thus providing added-security using encryption and network tunneling mechanisms. A VPN is like a bridge that connects two islands (here, LANs) to establish an private, secure and more reliable connection between the two islands (here, local networks). This helps ease security and privacy issues; since the data transmitted over a VPN is encrypted and unreadable to general Internet community. There are two types of VPNs, namely remote-access VPN and site-to-site VPN.

The main purpose of using both proxies and VPN services is to hide the IP Address of the users or to prevent tracking bodies and individuals from identifying their location. For example, this may even be used to access certain sites that are not otherwise accessible in the user's country. A lot of VPN providers also provide proxy services apart from providing VPN services. You can also use many public proxy servers at little to no charge.

Tor is a free software program that allows users to communicate anonymously. The name, Tor is an acronym that has been derived from the original name of the software project, which was The Onion Router. This software directs all Internet traffic and usage through a free volunteer network that exists worldwide, and has over six thousand relays to hide ip and location of the user; and hide Internet usage from individuals and authorities that are in charge of carrying out traffic analysis or network surveillance.

Did you lose your Android smartphone without installing a tracking app? If you're like most people, you realize that there are anti-theft or phone tracking app available for your Android smartphone after it's stolen or lost. It would be easier to track your phone if you have such app installed, but you still have a chance to track your phone and recover it. There are a couple of ways to track your phone if you use your Google Account linked to your phone.

Many readers of our website are contacting us for help on *allegedly* hacked IP address, and remedies for getting it back. One of the user is telling us his IP address used to be 64.3.x.y in Dallas and now it's 67.72.x.y located in Utah (per ip lookup); and hence his IP address is stolen, and his computer is running very slow and acting abnormal.

An IP address is an address assigned to a device on the Internet. It is analogous to postal address where a letter is delivered, and an IP address is computer's address where internet traffic is delivered. An IP address is assigned to you by your Internet Service Provider (ISP). When you signup with your ISP, your ISP either assigns you a static IP address or a dynamic IP address depending on the contract. If you need to setup a web server or an email service, you'll need a static IP address. If you are just browsing an Internet, you may just get by with a dynamic IP address.

A public IP address is an IP address that can be accessed over the Internet. Like postal address used to deliver a postal mail to your home, a public IP address is the globally unique IP address assigned to a computing device. Your public IP address can be found at What is my IP Address page. Private IP address, on the other hand, is used to assign computers within your private space without letting them directly expose to the Internet. For example, if you have multiple computers within your home you may want to use private IP addresses to address each computer within your home. In this scenario, your router gets the public IP address, and each of the computers, tablets and smartphones connected to your router (via wired or wifi) gets a private IP address from your router via DHCP protocol.
