I think I've got that right.
One major block of addresses reserved for special purposes is the IPv4 experimental address range 240.0.0.0 to 255.255.255.254. Currently, they cannot be used in IPv4 networks. However, these addresses could be used for research or experimentation.
In.addr-arpa (ali66reza)
Number 0 is used at the end of an IPv4 address for network identifiers and number 255 is used at end of an IPv4 for broadcast addresses.
When applying IPv4 addresses to router interfaces on a network, you would manually configure predictable addresses. For example, the lowest or highest address of the local subnet, on each particular router interface.
IP addresses are divided into five IP classes:IP address class AIP address class BIP address class CIP address class DIP address class E
The address space of IPV4 is limited to 4294967296 possible unique addresses.
Here are 3 facts about the network portion of an IPv4 address.Identical for all hosts in a broadcast domainVaries in lengthIs used to forward packets
192.169.32.1
In IPv4, the loopback address is 127.0.0.1. In IPv6 it is ::1.

IPV6 is less vulnerable to DNS Spoofing IPv4 addresses use 32 bit or 4 bytes for addressing IPv6 addresses use eight bit segments.
(Internet Protocol) IPv6 is the next step from IPv4. Currently we are not using IPv6 for our networks but soon it will implemented into our networks normally. IPv6 uses 128 bit spaces for its ip addresses were as IPv4 only uses 32 bit spaces. That means IPv6 can support 2128 addresses. I do not think we will run out of addresses with this version anytime soon.
