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.
An IP address is 32 bits long.
It is a 32 bit address.

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.
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.
