IP stands for Internet Protocol and v4 stands for Version Four (IPv4). IPv4 was the primary version brought into action for production within the ARPANET in 1983.
IP version four addresses are 32-bit integers which will be expressed in hexadecimal notation.
Example- 192.0.2.126 could be an IPv4 address.

Parts of IPv4

  • Network part:
    The network part indicates the distinctive variety that’s appointed to the network. The network part conjointly identifies the category of the network that’s assigned.
  • Host Part:
    The host part uniquely identifies the machine on your network. This a part of the IPv4 address is assigned to every host.

    For each host on the network, the network part is the same, however, the host half must vary.

  • Subnet number:
    This is the nonobligatory part of IPv4. Local networks that have massive numbers of hosts are divided into subnets and subnet numbers are appointed to that.

Characteristics of IPv4

  • IPv4 could be a 32-Bit IP Address.
  • IPv4 could be a numeric address, and its bits are separated by a dot.
  • The number of header fields are twelve and the length of the header filed is twenty.
  • It has Unicast, broadcast, and multicast style of addresses.
  • IPv4 supports VLSM (Virtual Length Subnet Mask).
  • IPv4 uses the Post Address Resolution Protocol to map to mack address.
  • RIP may be a routing protocol supported by the routed daemon.
  • Networks ought to be designed either manually or with DHCP.
  • Packet fragmentation permits from routers and causing host.
