IPv4 (internet Protocol version 4) is a network layer protocol that facilitates communication over a packet-switched network. It uses a 32-bit address scheme, allowing for approximately 4.3 billion unique IP addresses, which are divided into network and host portions. Data is transmitted in packets, each containing the source and destination IP addresses, and routed through various intermediary devices until it reaches its destination. IPv4 also employs techniques like subnetting and NAT (Network Address Translation) to manage address allocation and increase the efficiency of IP address usage.

IPv4 was described in RFC 791 in September 1981.
IPV4 is a kind of IP Address.
Minimal bytes required in IPv4 header are 20 i.e. 20 bytes are mandatory. And total bytes in IPv4 header are 60.
While IPv6 is based on IPv4, it is superior. The main characteristic that shows its enhancement over IPv4 is that it processes faster.
There is no need to disable ipv4 to use ipv6.
Hosts with the same network portion of their IPv4 address.
1. Describe the main features that differentiate IPv6 from IPv4
IP is the internet protocol that uniquely identifies a system on a network and there is no difference between IP and IPv4 infact IPv4 is a version of like IPv6.
