0.5 IP Address
INTRODUCTION
All the computers of the world on the Internet network
communicate with each other with underground or
underwater cables or wirelessly. If I want to download a
file from the internet or load a web page or literally do
anything related to the internet, my computer must have
an address so that other computers can find and locate
mine in order to deliver that particular file or webpage that
I am requesting. In technical terms, that address is
called IP Address or Internet Protocol Address.
An IP address is a unique address that identifies a device
on the internet or a local network.
IP stands for "Internet Protocol," which is the set of rules
governing the format of data sent via the internet or local
network.
 Types of IP Address:
1. IPv4
2. IPv6
Working of IP Address
The working of IP addresses is similar to other languages. It can
also use some set of rules to send information. Using these
protocols we can easily send, and receive data or files to the
connected devices. There are several steps behind the scenes.
Let us look at them

Your device directly requests your Internet Service Provider
which then grants your device access to the web.

And an IP Address is assigned to your device from the given
range available.

Your internet activity goes through your service provider, and
they route it back to you, using your IP address.

Your IP address can change. For example, turning your router
on or off can change your IP Address.

When you are out from your home location your home IP
address doesn’t accompany you. It changes as you change
the network of your device.
0.5 Address
 IP Address 10.0. 0.5 is a private IP address. Private IP
addresses are used inside a local area network (LAN) and are
not visible on the internet.
Private IP addresses are commonly used for local area
networks in residential, office and enterprise areas.
 Every device that connects to an internet network -- such as
computers, smartphones, tablets or printers -- will have a
private IP address.
 Routers need a way to identify these devices, and the
devices may also need to identify each other, which is where
private IP addresses come in.
 Private IP addresses are generated by a router for
identification.
 Private addresses can be assigned by the router
using the Dynamic Host Configuration Protocol or be
manually set, after which theaddresses communicate one
another with router.

How to protect IP address?
A Virtual Private Network (VPN) protects your anonymity on the
Internet by masking your IP address with a virtual one. When you
connect to the Internet through a VPN, websites see the IP
address assigned by a VPN server instead of the one assigned by
your ISP. If you're looking for more information about VPN - read
our recent article on the topic "What is VPN" - where you'll find
responses to all things VPN.
Changing your IP address with an international VPN server helps
change your geographical location drastically. For example, if
you’re in Canada connecting to the Internet with a United States
IP address, websites may think you’re connecting from the United
States instead of Canada.
Many services rely on IP addresses to check your location to
enforce copyright. So, theoretically, you could access Netflix USA
from outside of the United States with a VPN.
Online payment systems such as PayPal may also block access
to your account if you access it from an international IP address.
Theoretically, you can use a VPN to access the payment platform
in countries where it’s blocked.
 rivate IP addresses are commonly used for residential and
corporate networks, as the addresses cannot be seen outside
the private network.
 Internet service providers (ISPs) may also allocate a single
routable IPv4 address to residential customers
