THE GLOBEL FLOW OF IPV4 ADRESSESS
INTERNET PROTOCOL, or IP, is the base for internet communication; it is how unique addresses can be assigned to devices on a network. Today, there are two versions being used: IPv4 and IPv6. The following is a comprehensive comparison that will detail differences, advantages, and applications.
WHAT IS IPV4?
IPv4 is also called Internet Protocol Version 4. It came in the year 1981, and has 32-bit address space in itself, supporting nearly 4.3 billion unique IP addresses.
IMPORTANT IPV4 FEATURES:
32-Bit Addressing: The internet addresses are subdivided using dots like 192.168.1.1
Limited Address Space: In recent times, it has reached near exhaustion mainly due to increased Internet usage.
NAT : Allows a group of devices to share the same public IP.
Simple Scheme of Addressing: Easy to understand and simple to implement.
Broadcasting Communication: Data is sent to all nodes that are present in a network.
Static or Dynamic Configuration by DHCP: Either assigned statically or through DHCP, which is Dynamic Host Configuration Protocol.
Low Security : Doesn’t have in-built security measures.
Increases Network Congestion: This is because the available address space is low, also dependent on NAT.
Fragmentation: Fragments the packets while in transit.
Checksum Field: Intended to detect errors in packet headers.
