What are the ipv4 classes?
The IPv4 classes are A, B, C, D, and E. The A class is used for very large networks, class C for small networks, and class E is experimental.

What is the default subnet mask for IPv4?
There is no single default subnet mask; it depends on the class network you are using. Class A 255.0.0.0 Class B 255.255.0.0 Class C 255.255.255.0

Structure of an ipv4 address the types of ipv4 address available?
Structure of IP address IP address is used by routers, bridges and all kinds of end systems to focus data packets/frames on a particular destination/source port. Following de…fines the structure of a typical IP address. IPv4 address is 32 bit long. This 32 bit stream grouped into four segments. Each group may contain 1 byte (or 8 bits) 11000000 11100100 00010001 00111001 Each group of 8 bits can be converted to a decimal number. Following is the decimal conversion of above IP address. 192.228.17.57 This is the general look of an IP address. It will contain four decimal numbers separated by a dot. Each decimal can run up to 255. That is 255.255.255.255 . IP address gives many information about the network. For example; Example IP Address:192.248.8.0/28 This network ID is: 192.248.8.0. Hosts in this network: 32bit - 28 bit = 16 hosts Last IP (also known as Broadcast IP) = 192.248.8.15 The "/28" is not an integral part of IP address. We use this information is used to derive information from IP address. Types of IP Addresses IP Addresses are grouped into five classes. Class A - Class E. Class A: 1st bit of a class A IP address always has '0'. Next seven bits for network and rest 24 bits for host. CLass B: 1st two bits of a class B IP address always has '10'. Next 14 bits for Network and rest 16 bits for host. Class C: 1st Three bits of a Class C IP address has '110'. Next 21 bits for network and rest 8 bits for host. Class D: 1st Four bits of Class D IP Address has '1110' and rest of the bits are multicast. Class E: 1st Five bits has '11110' and rest of the bits are allocated for future usages.

What is ipv4 protocol?
Well IPv4 is actually just part of the protocol TCP/IP or Transmission Control Protocol / Internet Protocol. IPv4 is the current addressing scheme used by TCP/IP. The newer I…Pv6 has been rolling out to eventually replace IPv4. Back to what it is… IPv4 is a 32 bit binary addressing scheme by which every computer on the public Internet (most commonly HTTP) or web servers must be assigned a unique address. The address format is comprised of four sets of 8 bit numbers, more commonly referred to as an octet. So 4 * 8 binary numbers give you a 32 bit IPv4 binary address. Because these numbers are binary each place value only has two possibilities, 0 or 1. Because there are only around 4.3 billion addresses available with 2^32 possible IPv4 addresses a new IPv6 was developed which gives a 128 bit addresses space. This should last until there is no room to stand anywhere on the planet. To summarize IPv4 is not a protocol but an addressing scheme that TCP/IP uses to transmit data packets over the Internet or over a private network. Every computer that is directly connected to the Internet needs a unique address. There are what is known as private IPv4 addresses, different topic, and finally IPv4 will eventually be replaced by IPv6. (MORE)

What are three basic characteristics of ipv4?
IPv4 basic characteristics: Connectionless - No connection is established before sending data packets. Best Effort (unreliable) - No overhead is used to guarantee packet deliv…ery. Media Independent - Operates independently of the medium carrying the data. (MORE)

How large is a ipv4?
IPv4 goes from 0.0.0.0 to 255.255.255.255. There is a theoretical maximum of 4,294,967,296 unique addresses available, not including those behind NAT.

Why is IPv6 replacing IPv4?
"Because we will lose all IPv4 IP's when they run out." ------------------------------- I'm not sure what the respondent was trying to say here, but it doesn't come across as …accurate. The reality is that the TCP/IP addressing scheme (version 4) is limited. There are 4 "octets", comprised of 8 computer bits (ons or offs), that convert to numbers between 0 and 255, each separated by a "dot." For example, 192.168.2.1 If we did the math on all possible permutations of these four numbers (0.0.0.0 through 255.255.255.255) you can easily see that there are a limited number of possible adresses. And this number is fast being approached, even though some addresses are re-used for limited duration, as in so-called "dynamic" addressing. With IPv6, this number has been increased substantially. It is no longer limited by 4 octets. IPv6 promises dramatically more addresses for the future, though addressing complexity had to be increased to do it. Note that IPv4 and IPv6 were made to coexist with one another relatively seamlessly. Hence, we won't "lose all IPv4 IP's [addresses] when they run out." (MORE)

Why do we still use IPv4?
IPv4, The 32 bit Internet address scheme is still in use and most networks, whether or and off the internet, are still using IPv4 and have not yet switched over to the new…er IPV6. This is because their networks still work with IPv4; they feel there is no need to change what is not broken; not all equipment is capable of being switched to IPv6, and there may not be sufficient expertise to use IPv6. Also many internet service providers (ISPs) are not yet supporting it. Although we are running out of assigned IPv4 addresses, we can continue with the current scheme for a while longer using Classless Inter-Domain Routing (CIDR) which redistributes some unused class A and B Network addresses as smaller networks. We can also use Network Address Translation (NAT) to allows multiple machines in a local network to use a single external IPv4 address. The need for IPv6 is important to new Internet users who need a large number of externally visible internet addresses and the above methods are not sufficient. The use of the Internet-of-Things (IOT) when or if it ever becomes globally implemented and accepted will require a tremendous number of IP addresses and only IPv6 will be able to supply the required number of internet addresses for such personal devices.
