A public IP address is that your homeS or office router uses
to send and receive data to your Internet provider.A public IP address is
require for any network hardware device that is connected to the network such
as a router home, networking devices or servers hosting websites.
What does a public IP address do?
A public IP address differentiates devices that are connected
on the public Internet. Each devices that accesses the Internet uses a unique
public IP address. A public IP address and sometimes called the Internet IP.
It is the address that each Internet provider uses to send
Internet requests to homes and offices, similar to a delivery vehicle that uses
an address on the road to ship and deliver a package.

Imagine your public IP address as your home address. For
example, your e-mail address and your home address are unique to you, which is
why sending an e-mail to these addresses ensures that the message is not
delivered to someone elses.
The same exclusivity is apply to your IP address so that
your digital requests are sent over the network and not over another network.
Private IP address or public IP address: what's the difference?
A private IP address and, in many cases, the same as the
public one. It is a unique identifier for all device behind a router or other
device that uses IP addresses.
With a private IP address, devices at home can have the same
private IP address as those on your neighbor's or someone else's devices in the
world. This is because private addresses belong to hardware devices that cannot
be reached on the Internet or that are beyond a device that prevents them from
communicating directly to these devices that have a private IP address with
other IP addresses that are outside the range of the router.
Precisely because these private addresses are limited to the
scope of your home network and cannot be reached from the Internet, Yes you
need an address that can be reachable from the rest of the world, which is why
an IP address is required. Public This type of configuration enables all
devices on your home network to send information back and forth between the
router and the Internet provider using a single address (a public IP address).
Another way of explaining this system is to think of the
home router as an Internet provider. The router serves a private IP address to
its connected devices, just as an Internet provider assigns a public IP address
to devices that are publicly connect to the Internets.
Both privates and public addresses are used for
communications, but the scope of the communication is limited based on the
address that is used.
Both private and public add Both private and public
addresses are used for communication, but the communication range is limited
based on the address being use.
when you open a website from your computers, the request is
sent from your computer to Rutter with a private IP address, after which the
router requests the website from the internet provider using the public IP
address assigned to your network. Once the request has been made, the operation
takes place in the same way in reverse: the Internet provider sends the address
of the router website, which forwards it to their computers that have requested
it.
Range of public and private IP address
Certain IP address are reserve for public use and others for
private use.This is what makes an IP address private and therefore impossible
to reach from the public internet, as they are unable to communicate properly
until it exists. a router that acts as a bridge between the two networks.
The address 192.xxx is not publicly registered, which means
that it can only be used behind a Rutter as a private IP address. This range is
the one used in many private IP networks, and is also the reason why many home
Wi-Fi routers use it by default: Linksys, D-Link, Cisco, and NETGEAR use the
standard address 192.168.1.1.
The IPv6 address spaces is so large that the need for a
private IP address is not that important. However, there is a special unicast
range of IP addresses corresponding to fc00 :: / 7. In any case, this address
space is global.
How to find your public IP address
Probably, you will almost never need to know your public IP
address, but there are some situations where it is important or indispensable
to know it, such as being able to access your network or your computer when you
are away from home or the office.
The simplest and most basic example would be to use a
prog.To know your public IP address, ask this simple question to Google: what
is my public IP address. There are websites and Ute litigations that are able
to tell you in time real remote access frame. If you are in a hotel room, but
need to access your computer on the other side of the world, you just need to
know its Internet-accessible IP address (the public IP address your Wi-Fi
router uses) so that to configure the software to connect at the right point.
To find out your public IP address, ask Google this simple
question: what is my public IP address. There are websites and websites that
can tell you in real time.
Why does my public IP address change?
Many public IP addresses change quite often. Each type of IP
address that changes is called a dynamic IP address.
Many public IP addresses change quite often. Each type of IP
address that changes is called a dynamic IP address.
When you contact your Internet provider for the first time,
the user is connected to the Internet for a certain amount of time and then
disconnected. Whenever we make a new connection to the Internet through our
provider, we acquire a different public IP address, which is changed when the
connection drops or when we connect again.
This way of assigning IP addresses is related to the fact
that they are quite valuable on the public network and that the Internet
provider does not have enough of them to be able to grant a single public IP
address to each user who connects. In this way, all assigned addresses are
automatically recycled, as well as using some public IP address sharing
techniques called NAT (network address translation).
However, many networks that host websites have a static IP
address precisely because they want to make sure that users have constant
access to their servers. Having a changing IP address could make this
impossible, also because their address is registered within the DNS server
records Used to resolve names on the Internet: every time an address is
changed, these records must be updated, otherwise they would no longer be
reached by other users.
home networks, on the other hand, have assigned dynamic IP
addresses for the opposite reasons. If an Internet provider gave each home
network an address that does not change, it would be very likely that each
private user could abuse the service to host websites from home; or if you want
to take a security perspective, the fact that the same IP address never changes
would make life very simple for computer intrusions, making unwanted access
much easier and more probable.
This is the only reason that having a static IP address is
much more expensive than having a dynamic one. DDNS services have been
specifically designed to overcome these problems.
Another reason many networks have a changing public IP
address is that static IP addresses require more management and administration;
they often end up costing much more to a customer who uses a dynamic IP address
instead. For example, if you move to a new location a few kilometers away, but
use the same Internet provider, having a dynamic IP address assigned could
simply mean you cannot connect to this new location because this IP address is
not part of the address group. manageable in that position. Networks using
Static Addresses should be reconfigured for use in the new location.
Hide the public IP address
You cannot hide your public IP address from your internet
provider because all traffic has to move through this before reach anything
else on the internet. However, you can hides your IP address from the websites
you visit, as well as encrypt data transfers (hiding traffic from your Internet
provider) by first filtering your data through a WP N (Virtual Private
network).
normally, when you access a site, that site can see your
specific public IP address required to view that website. By doing a quick
search to find the IP address corresponding to your address, the website is
able to know from which location you are connecting and which Internet provider
you are using. Since your internet provider knows exactly which IP addresses
assigned to you, specifically, it could mean that a visit to that website can
be immediately traceable to you.
Using a WP N service adds another ISP at the end of your
request before you can open another website. Once connect to a VPN, the same
process as described above, only this time, is completely different: in this
case the website cannot trace directly to your IP address, but only to that of
the VPN servers to which you connect. you are connected.
Here's an example from Google displaying an IP address
before and after a VPN service is used:
Screenshot of a view of the public IP address with Google,
before and after a VPN connection
In this examples, if Google wanted to identify you, it
should request this information from the WP N service rather than your internet
provider, because again, it's the only IP address they see when you log into
the website then.
At this point, your anonymity depends solely on the VPN
service you are using, which obviously knows your identity perfectly. The
difference between many Internet providers and many VPN services is that it is
an Internet provider that is much more likely to provide data when some
government agency requests it to know which sites you have visited, rather than
a VPN service that may be hosted in countries. who do not have this type of
obligation. After all, these anonymous browsing services build their business
precisely on this.
There are numerous free and paid services from WP N that
offer many different features. If you are looking for one that does not save
browsing logs and traffic logs, I suggest that you only use a paid one and not
resort to free services on the Internet.

Hideman , Faceless.ME, and Windscribe VPN .

Routers have a default private IP address which is called
the default gateway. In a similar way to a home network that has an IP address
to communicate with the public Internet, a router has an IP address that
communicates with others connected to the private network.
Although the communications authority reserves a number of
IANA-allowed IP addresses, there are no centralized authorities that handle all
Internet traffic. If there is an external device that is attempting to breach
your network, there is no government authority that can protect you, save your
devices.
