# Best answer: What are the last 4 digits of IP address?

1. Address Class. Early in the development of IP, the IANA (Internet Assigned Numbers Authority) designated five classes of IP address: A, B, C, D, and E.
3. The Network Field.
4. The Host Field.
6. The Subnet Field.

Likewise, what are the 4 numbers after IP address? 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). High order bits are the network identifier and lower order bits are the host identifier.

Similarly, what do the last digits of IP address mean? The last number (which, as psusi mentions is called a subnet mask) indicates the number of relevant bits: /16 means the network includes all numbers starting with the first 16 bits of the specified ip (223.248 in your example).

Correspondingly, why are IP addresses 4 parts? The reason for dividing it into four sections is to identify the Class of the network. This helps to break your IP address into binary form and locate your device to transmit and receive data from the internet.

## What is the format of an IP address?

An IP address is typically written in decimal digits, formatted as four 8-bit fields separated by periods. Each 8-bit field represents a byte of the IP address. This form of representing the bytes of an IP address is often referred to as the dotted-decimal format.

## How many versions of IP are there?

There are two versions of IP in use today, IPv4 and IPv6. The original IPv4 protocol is still used today on both the internet, and many corporate networks.

## What do the first 3 numbers of an IP address mean?

The first 24 bits (the first three octets) identify the network and the remaining 8 bits indicate the host within the network. An example of a Class C IP address is 200.168. 212.226 where “200.168. 212” identifies the network and “226” identifies the host on that network.

## What are valid portions of an IP address?

For this purpose, an IP address is recognized as consisting of two parts: the network prefix in the high-order bits and the remaining bits called the rest field, host identifier, or interface identifier (IPv6), used for host numbering within a network.

## How do I know if an IP address is valid?

A valid IP address must be in the form of A.B.C.D, where A,B,C and D are numbers from 0-255. The numbers cannot be 0 prefixed unless they are 0.

## What is a 239 IP address?

Addresses starting with a number between 224 and 239 are used for IP multicast. IP multicast is a technology for efficiently sending the same content to multiple destinations. It is commonly used for distributing financial information and video streams, among other things.

## What is the IP address 0.0 0.0 used for?

IP address 0.0. 0.0 is used on servers to designate a service may bind to all network interfaces. It tells a server to “listen” for and accept connections from any IP address. On PCs and client devices.

## What is the third number in an IP address?

An IP address is a set of four numbers in the range of 0 to 255 separated by periods. Each of the four numbers is referred to as an octet. The first three numbers are used to identify the network segment, the third number identifies the device.

## What do IP numbers mean?

An IP address, or Internet Protocol address, is a series of numbers that identifies any device on a network. Computers use IP addresses to communicate with each other both over the internet as well as on other networks.

## What is IP packet format?

An IP packet is the smallest message entity exchanged via the Internet Protocol across an IP network. IP packets consist of a header for addressing and routing, and a payload for user data. The header contains information about IP version, source IP address, destination IP address, time-to-live, etc.

## What is Wi-Fi IP?

If you have Wifi Analyzer installed on your Android smartphone, launch the app. You will see the channel graph tab immediately. Swipe to the Access Points tab and you will see the IP address of your router.

## What are different types of IP address?

There are four different types of IP addresses: public, private, static, and dynamic. While the public and private are indicative of the location of the network—private being used inside a network while the public is used outside of a network—static and dynamic indicate permanency.

## What is the first version of IP?

The first major version of IP, Internet Protocol Version 4 (IPv4), is the dominant protocol of the Internet.

## What does 8 mean in IP address?

The “8” denotes that there are 24 bits left over in the network to contain IPv4 host addresses: 16,777,216 addresses to be exact.
