What do you know about reserved IPv4 addresses? Also, know about the different types of IPv4 addresses. Visit https://www.ipv4mall.com/ for more details.

1. RESERVED
IPV4
ADDRESSES

2. Some reserved IP addresses are unusable
on the web.
These IPv4 addresses have special
purposes, and it is not possible to route
these outside the LAN.

3. PRIVATE IPV4
ADDRESSES
All classes of IP have some addresses that are reserved in the form of private
Internet Protocol addresses.
It is possible to use these IP addresses in a network, company and campus,
plus these are private for that location.
It is possible to route these addresses on the web, so routers drop packets with
them.
Communicating with people who exist outside of the location requires
translating the addresses into some public addresses with NAT, or proxy
servers can be utilized for it.

4. PRIVATE IPV4
ADDRESSES
The only purpose of creating a separate private address range is to keep the allocation
of the already-limited IP address space in check.
By utilizing a private IP address range in LAN, the global demand for Internet Protocol
version 4 addresses has come down considerably.
It has helped to delay the IP address exhaustion process as well.
When utilizing the private range, it is possible to choose an IP class according to the
requirement and size of your organization.
A larger company may pick the class A address range while a smaller one may pick
class C. It is possible to further sub-net these addresses and allot them to departments
in a company.

5. LOOPBACK IPV4
ADDRESSES
People use the range of IP addresses 127.0.0.0 to127.255.255.255 only for loopback,
which is the self-address of a host, also called the localhost address.
The OS itself manages a loopback Internet Protocol address entirely.
The addresses allow for communication between the client and server processes on
one system.
When one process makes a packet through the destination address in the form of the
loopback address, that packet will be looped back to itself with no NIC interference.

6. LOOPBACK IPV4
ADDRESSES
The OS will forward data delivered on loopback to a VIF (virtual network interface)
in the OS.
The address is largely used as part of testing, such as client/server architecture for
one machine.
Besides that, when one host machine is capable of pinging any IP out of loopback
range, it suggests that the machine has a successfully loaded, working TCP/IP
stack.

7. LINK-LOCAL IP
ADDRESSES
Assume that a host cannot get an Internet Protocol address out of the DHCP
(Dynamic Host Configuration Protocol) server and that no IP address is allotted to
that machine manually.
In that case, it can allot itself an address out of a reserved Link-Local address
range.
It is impossible for the IP addresses to communicate as they belong to different
logical or physical segments.
It is also not possible to route these addresses.
