The Major Differences Between IPv4 and IPv6

  1. The IPv4 has 32-bit address length whereas IPv6 has 128-bit address length.
  2. The IPv4 addresses represent the binary numbers in decimals. On the other hand, IPv6 addresses express binary numbers in hexadecimal.
  3. The IPv6 uses end-to-end fragmentation while IPv4 requires an intermediate router to fragment any datagram that is too large.
  4. A Header length of IPv4 is 20 bytes. In contrast, the header length of IPv6 is 40 bytes.
  5. The IPv4 uses the checksum field in the header format for handling error checking. Even then, IPv6 removes the header checksum field.
  6. Into the IPv4, the base header does not contain a field for header length, and 16-bit payload length field replaces it in the IPv6 header.
  7. The option fields in IPv4 are employed as extension headers in IPv6.
  8. The Time to live field in IPv4 refers to as Hop limit in IPv6.
  9. The header length field which is present in IPv4 is eliminated in IPv6 because the length of the header is fixed in this version.
  10. IPv4 uses broadcasting to transmit the packets to the destination computers while IPv6 uses multicasting and anycasting.
  11. IPv6 provides authentication and encryption, but IPv4 doesn’t provide it.

IPv4 is 32-Bit IP address whereas IPv6 is a 128-Bit IP address.

IPv4 is a numeric addressing method whereas IPv6 is an alphanumeric addressing method.

IPv4 binary bits are separated by a dot(.) whereas IPv6 binary bits are separated by a colon(:)
