What are the characteristics of IPv4?

IPv4 Features and Characteristics
  • 32-Bit address with numeric characters separated by dots.
  • It uses post address resolution protocol in mapping to mac address.
  • 12 header fields.
  • Contains Unicast, Multicast, and broadcast addresses style.
  • Manual assignment or through DHCP.

What are IPv4 and IPv6?

The Internet Protocol version 4 (IPv4) is a protocol for use on packet-switched Link Layer networks (e.g. Ethernet). IPv4 provides an addressing capability of approximately 4.3 billion addresses. The Internet Protocol version 6 (IPv6) is more advanced and has better features compared to IPv4.

Which are the features present in IPv4 and not in IPv6?

Explanation: An IPv6 address is 128 bits long. Therefore, 2128 i.e. 340 undecillion addresses are possible in IPv6. IPv4 has only 4 billion possible addresses and IPv6 would be a brilliant alternative in case IPv4 runs out of possible new addresses.

What is the function of IPv6?

The primary function of IPv6 is to allow for more unique TCP/IP address identifiers to be created, now that we’ve run out of the 4.3 billion created with IPv4. This is one of the main reasons why IPv6 is such an important innovation for the Internet of Things (IoT).

Which is faster IPv4 or IPv6?

In general, there’s no major difference between IPv4 vs IPv6 speeds, though some evidence does suggest that IPv6 might be slightly faster in some situations.

What is the difference between IPv4 and IPv6 header?

The main difference between IPv4 and IPv6 Header is that the source and destination addresses of IPv4 header are 32 bit long while the source and destination addresses of IPv6 header are 128 bits long.

What is IPv4 used for?

Internet Protocol version 4 (IPv4) is the fourth version of the standard that routes Internet traffic and other packet-switched networks introduced in 1982 by the Internet Engineering Task Force (IETF). IPv4 is the most widely used version of the protocol despite the limitations of its 32-bit address space.

What are the different types of IPv6 addresses?

The three types of IPv6 addresses are: unicast, anycast, and multicast. Unicast addresses identify a single interface. Anycast addresses identify a set of interfaces in such a way that a packet sent to an anycast address is delivered to a member of the set.

What is an example of an IPv6 address?

The following list shows examples of valid IPv6 (Normal) addresses: 2001 : db8: 3333 : 4444 : 5555 : 6666 : 7777 : 8888. 2001 : db8 : 3333 : 4444 : CCCC : DDDD : EEEE : FFFF.

Why does IPv6 have 128 bits?

Basically, the 128-bit address space of IPv6 gives us such a massive address space that we are unlikely to ever use all of it (2^128 addresses, or 3.4*10^38). The larger address space also allows for a better hierarchical model of addressing, because CIDR and similar “hacks” are no longer necessary for routing.

How many IP addresses are there in IPv6?

340 trillion trillion trillion IP addresses
IPv6 uses 128-bit (2128) addresses, allowing 3.4 x 1038 unique IP addresses. This is equal to 340 trillion trillion trillion IP addresses.

What is IPv4 example?

IP (version 4) addresses are 32-bit integers that can be expressed in hexadecimal notation. The more common format, known as dotted quad or dotted decimal, is x.x.x.x, where each x can be any value between 0 and 255. For example, 192.0. 2.146 is a valid IPv4 address.

What is the size of IPv4?

32 bits
An IPv4 address is 32 bits. An IP Address is shown as 4 decimal numbers representing 4 bytes: d.d.d.d where d = decimal number (0 – 255).

What are three parts of an IPv6?

Three basic parts that make up the address are the routing prefix, the subnet ID and the interface ID. An example of the different segments of an IPv6 address.

What are the three basic characteristics of IPv4?

Characteristics of IPv4

It has Unicast, broadcast, and multicast style of addresses. IPv4 supports VLSM (Virtual Length Subnet Mask).

What are the advantages of IPv4?

Advantages of IPV4:

IPV4 is necessary to encrypt data to ensure privacy. It takes security measures to encrypt data in its address packets. IPV6 protocol can be easily supported by most of the topology drawings. Since addresses are combined more effectively the process of routing has become more efficient in IPV4.
