Before we can talk about faking an IP address, we need to know what an IP address is and how it is used. An IP Address is an unique address assigned to a computing devices such as a computer, tablet or smartphone. An IP address is analogues to postal address of a house (or phone number of your smartphone), where two houses cannot have the same address as a mailman will be confused where to deliver the mail. Similarly, an IP address must be unique within the globe so that a message can be delivered to an intended device.

One of the biggest challenges with online stores is detecting and preventing fraudulent orders. Fraudsters attempt to use stolen credit cards to purchase goods online, and sometimes such transactions do go through without detection. If a fraud chargeback occurs, it is the merchant's responsibility to prove to the bank that the charge was made legitimately. If you can't prove the legitimacy, the money will be withdrawn from your bank and you can't do much about it.

Technology has come a long way and is constantly evolving every day and it's no exception with geolocation. Thanks to this, geolocation has found a very strong and everyday use in today's world. RFID (radio frequency identification) tags have come about as a result of this and function as neat little devices which can be tagged to other items that have no means of connecting to the Internet. Through this, one can then geolocate these tags and their tagged objects.

What is a Web Bug (Beacon)?

A web bug is also referred to as web beacon, pixel tag, clear GIF, invisible GIF. It is one of the techniques used in emails or web pages to check what the user has accessed. These are in most cases invisible and are used for web analytics. In most cases, web bug arrives in the form of an image and can be detected by the user only if the source code is checked. A web bug is small graphic and hence can work easily with low bandwidth or weak network connection.

Most of us believe that our IP address can be tracked only by the Internet Service Provider. Did you know that there are multiple ways in which someone can spy on your IP address? Anybody knowing one of these techniques can easily reveal your IP address. To spy on your IP address, they do not need your permission. Spying on someone's IP address can be used to trace cyberbullying as well as bad intentions.

The private IP addresses are the reserved IP address blocks that cannot be routed through the internet. Since private IP addresses are only intended to be used in private networks, they are not globally unique. The private IP address must be unique within its network (usually LAN) so that there is no conflict between two computers within its network. Due to scarce nature of IPv4 Address (i.e. approximately 4 billion IP addresses), IANA reserved private IP address blocks so that they can be used by any organization without registering them with IANA. The private IP address block can be used in homes, small businesses, or even medium and large enterprises to create their own network. Computing devices with a private IP address cannot be directly accessed from the Internet unless NAT (Network Address Translation) is used. The advanced network planning techniques have also enabled network planners to use same private IP address within different private networks thus allowing them to save valuable IP address space. A private address may also be referred to as a local IP address. It also enables to hide the identity of the users over the Internet.

By finding IP address of yourself or a person you wish to lookup, the geolocation lookup tool provide you with an estimate of where this IP address is located. American Registry of Internet Numbers, also known as ARIN, maintains the Whois Database containing contact and registration information for IP addresses. The companies requiring IP addresses obtain and register them with ARIN, and those IP addresses obtained are assigned to their users and customers. Internet Service Providers (ISPs) assign a dynamic IP address to a user when their customers connect to the Internet. Since a company may be located throughout a large region (or a country), the accuracy of geolocation may vary depending on how they assign them to their users.

To connect your computer to the Internet, you'll need an IP address. If your computer is directly connected to the gateway (or switch) provided by your ISP, your computer gets a public IP address from your ISP. However, if your computer is connected to the Internet via a router within your home network, your computer gets a private IP address from your router and your router gets the public IP address from your ISP.

IP ban is a block setup by a server to reject request made from a particular IP or range of IP addresses. The IP ban may have been implemented automatically due to abuse pattern detected by the server or placed manually by an administrator. IP ban is implemented to protect the server from abuse such as brute force attacks, block emails from known spammers and limit usage by users. IP Ban allows a server to ban an IP address from accessing a website, forum, email or game server.
