Introduction to IP addressThe full form of the IP address is Internet Protocol address. Its the unique numeric number assigned to each device connected to computer network that uses internet protocol scheme. IP address is used for unique identification of the device.
Your computer is internally connected to the internet network, one way or the other. When you connect online, to perform any activity, your request has to be sent to the ISP and it connects you on network and assign an IP to your device.
Your device actually connect to the internet network indirectly. The network is your Internet service provider (ISP) or a company network at work place, or a WiFi. There are billions of computers connected on the Internet, how can your device Jump right in without any issues ?
Introduction to IPv4 and IPv6The Internet Protocol version 4 (IPv4) which is a protocol for use on packet-switched Link Layer networks (e.g. Ethernet). IPv4 provide an addressing capability of 4.3 billion addresses.
The Internet Protocol version 6 (IPv6) is more advanced and has better features compared to IPv4. It has the capability to provide an infinite number of addresses. It is replacing IPv4 to help solving the IP address exhaustion problem.
Difference between IPv4 and IPv6The major differences between IPv4 and IPv6 is the appearance. IPv4 uses decimal numbers, separated by a dot (i.e. 192.168.1.2), but IPv6 uses hexadecimal numbers that are separated by colons (i.e. fe80::d4hh8:64g5:dfdd:d9f3b11). Actually IPv4 addresses are 32 bit length but IPv6 addresses are 128 bit length.
Ipv6 can give addresses upto a limitations and according to a survey the Ipv4 addresses are almost over but Ipv6 addresses can provide the addresses up to infinity because they are the collection of numbers and alphabets with a long pattern.
Compatibility to mobile network of Ipv6 is great than Ipv4. IPv4 is the most widely used Internet protocol used to connect devices to the Internet and according to a survey the IPv6 addresses are started in use but still 99% of the network uses Ipv4 addresses.
