Perhaps you refer to IPv4. That is internet Protocol version 4, the currently used version of IP.
IMPROVED:
IPv4 is the older standard of internet protocol that is still in predominant use today. While it is the most popular, it does have some limits in the realm of performance, and there is a maximum number of IP addresses possible in IPv4 which we are rapidly approaching. When this maximum is met, websites will have to move to IPv6 in order to allow new sites to launch. As such, many major sites are porting to IPv6 as we speak, since it has a much higher limitation.
IPv4 addresses use four sets of 8-bit numbers (called Octals) that look like so:
192.168.1.1
Each of the four octals, being 8-bit, cannot exceed 255 or go below 0, which is the maximum addressible space for an 8-bit sequence (256 digits, or 0-255)
IPv4 is limited to 4,294,967,296 possible Ips. Realistically the number is much lower, as most ISPs will reserve IP blocks for themselves or specific uses. For example: 192.168.x.x is typically reserved for internal networks, and 128.x.x.x is reserved for local resources. Many others, such as 10.x.x.x are also reserved for other purposes, such as multicast networks.
IPv6 does not have this limitation.

What is the difference between ipv4 and ip address?
IPV4 is a kind of IP Address.
Minimum bytes in IPv4 header?
Minimal bytes required in IPv4 header are 20 i.e. 20 bytes are mandatory. And total bytes in IPv4 header are 60.
Which characteristic describes an IPv6 enhancement over IPv4?
While IPv6 is based on IPv4, it is superior. The main characteristic that shows its enhancement over IPv4 is that it processes faster.
Should ipv4 be disabled when using ipv6?
There is no need to disable ipv4 to use ipv6.
