Every device connected to the Internet needs to have an identifier. Internet Protocol (IP) addresses are the numerical addresses used to identify a particular piece of hardware connected to the Internet.
The two most common versions of IP in use today are Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6). Both IPv4 and IPv6 addresses come from finite pools of numbers.
For IPv4, this pool is 32-bits (232) in size and contains 4,294,967,296 IPv4 addresses. The IPv6 address space is 128-bits (2128) in size, containing 340,282,366,920,938,463,463,374,607,431,768,211,456 IPv6 addresses.Full Detail

Thankfully, modern hardware and software has reduced the complexities of configuring networks down to a few setup screens, and the relevant hardware often comes free with an internet connection.
If you have multiple computers, the chances are they're already talking to each other, either through wires or wirelessly. However, while your home network might be up and running, optimising it takes some doing. Follow our simple tips to extract the last drop of juice from your network hardware.Full Detail
When you are on the internet or are working in an networked environment you may think you have problems with your network connection. However it would be helpful if you could diagnose whether there is a problem and what it is.

Most of the tools on this page are accessed from the DOS or Command prompt. While this can look a little scary to a novice user, it can be quite powerful and allow you to manipulate your system and see what is going on in a a way that isn't possible with nice looking GUI (Graphic User Interface) tools. However if you are a novice to the Command Prompt, then you should read our getting started guide.Read More
