IP addresses are of two types IPV4 and IPV6 . Depending upon the version the length of IP address differs . IPV4 is 32 bit long and IPV6 is 128 bits long.

The address space of IPV4 is limited to 4294967296 possible unique addresses.

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 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.
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.
Understanding IPv4 addresses is crucial because they are fundamental to internet connectivity and communication. Each device on a network requires a unique IPv4 address to send and receive data, making it essential for routing traffic efficiently. Furthermore, knowledge of IPv4 helps in troubleshooting network issues and managing network security effectively. As the internet continues to grow, understanding IPv4 also lays the groundwork for transitioning to IPv6, which addresses the limitations of IPv4.
IPv4 addresses are 4 bytes. IPv6 IP addresses are 16 bytes.
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.
While IPv6 is based on IPv4, it is superior. The main characteristic that shows its enhancement over IPv4 is that it processes faster.
