What is an Internet Protocol (IP) address?
You frequently hear about the so-called IP address. However, what is an IP address? The IP address is comparable to the street address of a home. For example, this address can be used to locate the residence and deliver mail. This method is also used on the Internet to ensure that data is sent to the correct computer. The Internet Protocol is the network protocol employed in this case (IP).
Each computer connected to the Internet has one or more IP addresses. This unique address can be used to identify the Internet-connected device. This is the only way to assure that the computer receives the data it requests. When a web page is requested, the browser broadcasts the computer's IP address. This provides a delivery address for the server from which the data is to be retrieved. The IP address is the only means for the asking machine to receive the requested data.
What is the format of an IP address?
The IP addresses associated with the previous IPv4 standard are well-known. In this case, the IP address is comprised of four integers ranging from 0 to 255. The four digits of the IP address are separated by dots, resulting in an IP address that looks like this: 22.214.171.124.
However, because this older variant can only represent a finite amount of IP addresses, there is the newer IPv6 standard. This IP address is substantially longer and includes both letters and numbers. The IP address is made up of eight character blocks; zeros may be replaced with colons to make the IP address more readable.
IP addresses may be static or dynamic in nature.
The IP address can be used to determine the provider that assigned the address and the device's approximate location. However, because IP addresses are often reissued for each Internet session, a device's IP address does not always remain the same. This is because providers typically have a limited amount of addresses and distribute them on a need-to-know basis, as no user will ever be online simultaneously. However, in addition to dynamic IP address assignment, static addresses are also used, for example, for servers and leased lines. Private customers, on the other hand, are typically assigned a dynamic IP address.
How IP addresses are assigned in a home network?
At first, these provider allocations in your own home may go unnoticed. The customer's own devices, whether PC or smartphone, are not directly connected to the Internet, but rather to the router at home, which serves as a gateway for all requests - the router is effectively an Internet distributor. Dynamic IP addresses are frequently used in residential networks as well. These are issued by the router internally but are not visible to the rest of the world.
How can I determine my IP address?
The address accessible on the Internet, i.e. the router's address, is frequently easiest to locate by inquiring in a courteous manner to your trusted search engine: "What is my IP address?" or by visiting our site.
It's not quite as simple with internal addresses. Under Control Panel - Network and Internet - Network and Sharing Center, for example, you must pick your own Internet connection by clicking on the corresponding link and then selecting "Details."
How does atozseotools.net determine my service provider?
Each provider is assigned a specific IP range to assign addresses from. This is because public IP addresses are required to be unique and hence cannot be assigned more than once. The list of which providers possess which IP ranges is public. We can determine which Internet service provider you use based on this data.
Atozseotools.net IP checker shows the wrong location
An IP address can only be associated with you and your domicile by your provider; third parties (such as atozseotools.net) can only make educated guesses about your location. While this strategy is relatively reliable in urban areas, it is occasionally wrong in rural areas.
When do I need to know my IP address?
Of course, there are a variety of reasons to wish to know your own IP address - but you will always need to know it when another computer outside your network attempts to access your computer. This is true, for example, if you wish to act as a host in a computer game, if you like to move your desktop to a friend for assistance, or if you wish to access your desktop PC at home while traveling.
What if I am using a proxy server?
Atozseotools.net attempts to determine on its own whether you are using a proxy or directly accessing the internet. Atozseotools.net will attempt to determine your true IP address if it detects a proxy. If this is successful, a hint will appear beneath the public IP address. If no hint is displayed, we were unable to detect a proxy or determine your true IP address.
Can my IP address change?
Private users are typically allocated dynamic IP addresses, which means they are assigned a new address on a regular basis by the provider. The frequency with which this occurs varies by the provider; in the meantime, a new IP address is often assigned only after the provider's connection has been disrupted and reestablished. A static IP address is typically allocated to corporate customers - this is critical because businesses frequently provide server services (for example, a web server for operating websites). If the address at which this server may be accessed changes on a regular basis, this could result in unexpected inaccessibility.
Internet service providers can determine which connection's owner was issued which IP address at what time. Providers are required to give this information to investigating authorities in the event of a criminal investigation. This is true for dynamic as well as static IP addresses. Tools like atozseotools.net's "What's my IP" can only predict which Internet provider you use - but not who you are or where you live.
Dual-Stack: IP4 and IP6
The IP address, which consists of 4 blocks of numbers, is also called IPv4 or 32-bit IP address. With this system, about 4 billion combinations are possible. That is much, much less than there are devices connected to the Internet. Especially in terms of smart homes, much more IP addresses will be needed in the near future. Because now everything from smart TVs to smart refrigerators needs an IP.
At the beginning of the Internet, people simply didn't expect how many users it would one day have. Because there were far too few IP addresses, DynDNS and NAT were used: In simple terms, this means that different users are assigned to a common IP address.
In addition to the 32-bit system, there is now also a 128-bit system called IPv6. With this, instead of the only four billion number codes with IPv4, around 340 sextillion addresses are available through IPv6. The parallel operation of both systems is called dual-stack.
At the moment, both IPv4 and IPv6 addresses are used, although the switch to IPv6 will be made in the distant future. For the changeover, there will be network nodes that can handle both forms. However, all services will probably remain under both the old and the new address for the next few years.
