IPv4 basic characteristics:
Connectionless - No connection is established before sending data packets.
Best Effort (unreliable) - No overhead is used to guarantee packet delivery.
Media Independent - Operates independently of the medium carrying the data.
IPv4 basic characteristics: Connectionless - No connection is established before sending data packets. Best Effort (unreliable) - No overhead is used to guarantee packet delivery. Media Independent - Operates independently of the medium carrying the data.
The first characteristic is that the IPv4 is completely connectionless. The second is that they are media independent and can be unreliable.

IPv4 was described in RFC 791 in September 1981.
The IPv4 address is identical for all hosts in a broadcast domain. The IPv4 addresse varies in length. The IPv4 address is used to forward packets.
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.
There is no need to disable ipv4 to use ipv6.
Hosts with the same network portion of their IPv4 address.
