What Is A IPV4?

100% Uptime SLA, 24/7/365 Live Support & Fast Cloud Servers

The first version of IP was IPv4. In 1983, it was deployed in the ARPANET for development. It is the most commonly used version of IP today. It is used to use an addressing scheme to classify devices on a network.

IPv4 uses a 32-bit address scheme that allows more than 4 billion addresses to store 2 ^ 32 addresses. It is known to be the main Internet Protocol to date and carries 94% of Internet traffic.

Features of IPv4

  • Connectionless Protocol
  • Allow creating a simple virtual communication layer over diversified devices
  • It requires less memory, and ease of remembering addresses
  • Already supported protocol by millions of devices
  • Offers video libraries and conferences

Key differences between IPV4 and IPV6

  • 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 (:).
  • IPv4 offers 12 header fields whereas IPv6 offers 8 header fields.
  • IPv4 supports broadcast whereas IPv6 doesn’t support broadcast.
  • IPv4 has checksum fields while IPv6 doesn’t have checksum fields
  • IPv4 supports VLSM (Virtual Length Subnet Mask) whereas IPv6 doesn’t support VLSM.
  • IPv4 uses ARP (Address Resolution Protocol) to map to MAC address whereas IPv6 uses NDP (Neighbour Discovery Protocol) to map to MAC address.
