What Is My IP Address?
Your not alone, many internet users wonder, “what is my IP address”? Many use the internet for anonymity, tech support, proxy detection, desktop connection or even gaming.
Their is a need to see if an IP address has changed. However, in the case of email servers or web servers, it’s important to use what is called a static IP address.
You can quickly determine your IP address or the IP address of another device. An IP address is a logical address of a network adapter, and every network device has one. An IP address is a unique number that identifies computers on a network, so an IP address can easily be used to determine the location of a device or origin of an internet message.
Find your own IP address. Maybe you want to figure out who sent you an email, or perhaps you’re curious as to who posted a message you read online. If you have the IP address of origin, you can easily use our free IP lookup service to find out.
What Is My IP Address?
IP addresses can be either static or dynamic. Static IP addresses never change. They serve as a permanent Internet address and provide a simple and reliable way for remote computers to contact you. Static IP addresses reveal such information as the continent, country, region, and city in which a computer is located; the ISP (Internet Service Provider) that services that particular computer; and such technical information as the precise latitude and longitude of the country, as well as the locale, of the computer. Many websites provide IP address look-up services to their visitors, free of charge. If you’re curiously asking “What Is My IP Address?“, you can locate these websites by performing a Google search.
Dynamic IP addresses are temporary and are assigned each time a computer accesses the Internet. They are, in effect, borrowed from a pool of IP addresses that are shared among various computers. What Is My IP Address? Since a limited number of static IP addresses are available, many ISPs reserve a portion of their assigned addresses for sharing among their subscribers in this way. This lowers costs and allows them to service far more subscribers than they otherwise could.
Static IP addresses are generally preferable for such uses as VOIP (Voice over Internet Protocol), online gaming, or any other purpose where users need to make it easy for other computers to locate and connect to them. Easy access can also be facilitated when using a dynamic IP address through the use of a dynamic DNS service, which enables other computers to find you even though you may be using a temporary, one-time IP address. This often entails an extra charge, however, so check with your ISP.
Static IP addresses are considered somewhat less secure than dynamic IP addresses, since they are easier to track for data mining purposes. However, following safe Internet practices can help mitigate this potential problem and keep your computer secure no matter what type of IP address you use.
- Class A addresses are for large networks with many devices.
- Class B addresses are for medium-sized networks.
- Class C addresses are for small networks (fewer than 256 devices).
- Class D addresses are multicast addresses.
The first few bits of each IP address indicate which of the address class formats it is using. The address structures look like this:
Class A
| 0 | Network (7 bits) | Local address (24 bits) |
Class B
| 10 | Network (14 bits) | Local address (16 bits) |
Class C
| 110 | Network (21 bits) | Local address (8 bits) |
Class D
| 1110 | Multicast address (28 bits) |
The IP address is usually expressed as four decimal numbers, each representing eight bits, separated by periods. What Is My IP Address? For Class A IP addresses, the numbers would represent “network.local.local.local”; for a Class C IP address, they would represent “network.network.network.local”.
