In Microsoft Windows, you can enter ipconfig in the command prompt app to view your computer's current IP address configuration.

Every machine on a network has a unique identifier. Just as you would address a letter to send in the mail, computers use the unique identifier to send data to specific computers on a network. Most networks today, including all computers on the , use the TCP/IP protocol as the standard for how to communicate on the network. In the TCP/IP protocol, the unique identifier for a computer is called its IP address.
There are two standards for IP addresses: IP Version 4 (IPv4) and IP Version 6 (IPv6). All computers with IP addresses have an IPv4 address, and many are starting to use the new IPv6 address system as well. Here's what these two address types mean:
Keep Reading Below
IPv4 uses 32 binary bits to create a single unique address on the network. An IPv4 address is expressed by four numbers separated by dots. Each number is the decimal (base-10) representation for an eight-digit binary (base-2) number, also called an octet. For example: 216.27.61.137IPv6 uses 128 binary bits to create a single unique address on the network. An IPv6 address is expressed by eight groups of hexadecimal (base-16) numbers separated by colons, as in 2001:cdba:00:52. Groups of numbers that contain all zeros are often omitted to save space, leaving a colon separator to mark the gap (as in 2001:cdba::).
At the dawn of IPv4 addressing, the Internet was not the large commercial sensation it is today, and most networks were private and closed off from other networks around the world. When the Internet exploded, having only 32 bits to identify a unique Internet address caused people to panic that we'd run out of IP addresses. Under IPv4, there are 232 possible combinations, which offers just under 4.3 billion unique addresses. IPv6 raised that to a panic-relieving 2128 possible addresses. Later, we'll take a closer look at how to understand your computer's IPv4 or IPv6 addresses.
How does your computer get its IP address? An IP address can be either dynamic or static. A static address is one that you configure yourself by editing your computer's network settings. This type of address is rare, and it can create network issues if you use it without a good understanding of TCP/IP. Dynamic addresses are the most common. They're assigned by the Dynamic Host Configuration Protocol (DHCP), a service running on the network. DHCP typically runs on network hardware such as
or dedicated DHCP servers.
Dynamic IP addresses are issued using a leasing system, meaning that the IP address is only active for a limited time. If the lease expires, the computer will automatically request a new lease. Sometimes, this means the computer will get a new IP address, too, especially if the computer was unplugged from the network between leases. This process is usually transparent to the user unless the computer warns about an IP address conflict on the network (two computers with the same IP address). An address conflict is rare, and today's technology typically fixes the problem automatically.
Next, let's take a closer look at the important parts of an IP address and the special roles of certain addresses.

Browse RelatedAbout Paint Thickness GaugeQuite often it helps to know how many layers of paint are on an object, whether that is a desk you plan to refinish or a car you are planning to buy. Those are the type of situations when a paint thickness gauge comes in handy. This is a small device that can actually measure paint layers in microns. A micron is a millionth of a meter, which definitely cannot be measured by the human eye, but a digital thickness gauge can measure that for you and display the number of microns of thickness that are on an object. Once you have the number, you can estimate paint layers, which helps you to plan how to either attack that desk or what to ask the used car dealer. An ultrasonic thickness gauge uses ultrasonic waves to do the measuring for you, rather than the sensors in a typical digital gauge. With the vast inventory on eBay, you can find a paint thickness gauge for all of your needs, even if you never thought that measuring paint thickness was important information to have.Additional site navigationCopyright (C)
