The main difference between IPv4 and IPv6 is that Ipv4 works on quad format whereas IPv6 doesn't support that format. Secondly, IPv6 has more features as compared to IPv4. IPv4 is discussed first as it is easier to understand the quad notation and other features of IPv4.
IPv4 and IPv6 differ in address formats, with IPv4 using 32-bit addresses and IPv6 using 128-bit addresses. IPv4 is discussed first in texts because it was the initial and widely adopted version, serving as a foundation for understanding networking. The need for IPv6 arises due to the exhaustion of IPv4 addresses.
In IPv4 , the address notation is called dotted-quad sequence. IPv4 is 32 bit address and IPv6 and 128 bit address.It is widely adopted and its easier to read addresses
the fundamental diff between ipv4 and ipv6 is length ipv4 length is 32 bit whereas ipv6 is 128 bits. and second is in ipv4 uses deciaml format and ipv6 uses hexadecimal format.
difference between IPv4 and IPv6 is that Ipv4 works on quad format whereas IPv6 doesn't support that format. IPv4 is 32 bit address and IPv6 and 128 bit address
