The public IP address is the IP address that your home or business router receives from your ISP. For any publicly available network hardware, a public IP address is required, such as: For example, for your home routers and servers hosting.

Public IP addresses publicize all plug-in devices on the Internet. Every device that uses the Internet uses a unique IP address. In fact, public IP addresses are sometimes referred to as Internet IP.

It is well known that any Internet service provider prompts Internet requests for a particular home or business, eg. For example, a delivery vehicle that uses your physical address to forward your house packages.

Think about your public IP address because you have a different address. For example, your e-mail address and home address are unique to you. Therefore, sending emails to this address ensures that they really come to you, not to others.

The same specificity applies to your IP address, so your digital requests are sent to your network … and not to third parties.

Private Vs. Public IP addresses

In most cases a private IP address is the same as a public IP address. This is a unique identifier for all devices behind the router or other device that provides IP addresses.

However, in contrast to the public IP address, your home appliances may have private private IP addresses, such as your neighbor's device or anyone else in the world. This is because private address routers are not. On the Internet, hardware devices are programmed to prevent other IP addresses from communicating with other IP addresses directly from the router.

Since these private addresses are not found on the Internet, you need an address that can reach the rest of the world. For this reason, a public IP address is required. This type of setup allows all the devices on your home network to carry forward information through a single address (public IP address) between your router and ISP.

Another way to see this is to consider the router as your internet service provider in your home. When your router provides a private IP address on the personalized connected device behind your router, your ISP provides public IP addresses on public devices that are publicly connected to the Internet.

Both private and public addresses are used for communication. However, this communication limit is limited to addresses used.

When you try to open a web site from your computer, the request is sent from your computer as a private IP address to your router. After that, your router uses the public IP address assigned to your website by your ISP. Is there. Once requested, the operation is rolled back - the ISP sends the address of the web site to your router, which recognizes the computer being asked for it.

The range of public IP addresses

Some IP addresses are reserved for public use, others for personal use. Because of this, private IP addresses can not use the public Internet because they can communicate properly only when they are behind the router.

The following categories are reserved by the Internet Asset Number Number Authority (INAA) to use as a private IP address:

10.0.0.0 to 10.255.255.255
172.16.0.0 to 172.31.255.255
19 2,168.0.0 to 19 2,168,255,255
Except the above address, the public IP address is "1 …" to "191 …".

All "192 …" addresses are not publicly registered and therefore only used as a personal IP address behind the router. This is the area where most private IP addresses are located. For this reason, the default IP address for most links, D-Link, Cisco and Netgaur router is an IP address within this group.

How to get your public IP address

You do not usually need to know your public IP address, but there are situations where this is important or necessary, such as: For example, if you want to reach your network or computer, stay away from home or away from your home business.

The most basic example would be if you use a remote access program. For example, if you are in the hotel room in Shanghai, but at your Denver Home, on your home computer, you need to know the IP address that can be reached on the Internet. IP address uses your home routers.) So you can instruct the software to connect to the right place
