The address space of IPV4 is limited to 4294967296 possible unique addresses.
IPv4 Mechanisms
That's an iPv4 address. (4 bytes, 32 bits)

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.
IPv6 has a larger address space compared to IPv4, allowing for more unique addresses. This solves the issue of address exhaustion seen in IPv4.
There is no need to disable ipv4 to use ipv6.
Hosts with the same network portion of their IPv4 address.
