What Do The Four Numbers In An IP Address Mean?

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.

What do the numbers mean after an IP address?

It indicates the subnet mask of the IP. IP has 32 bits, and number after the slash

tells you where does the network part end, host part starts

. and /24 says that first 24 bits are used for network designation, while last 8 bits are used for various hosts inside that network.

What are the 4 parts of an IP address called?

• Default Subnet Mask. …
• The Network Field. …
• The Host Field. …
• Non-default Masks. …

Can an IP start with 4 numbers?

Your IP address

and everyone else’s is

made up of four fields of numbers separated by three dots. (Go to the WhatIsMyIPAddress home page to see yours right now.) You can read each field as its own number, which can range from 0 to 255.

What does each section of an IP address mean?

249.145, every IP address is split into two sections, which define your network and your host or computer. Those two parts make up the fundamental structure of IPv4 addresses:

the host ID and the network ID

. Each computer on the same network shares the same network ID, and each one has its own host ID.

What does 8 mean in IP address?

What is the 3rd octet of an IP address?

To perform subnetting,the third octet (in this example) is

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.

How many digits are IP addresses?

32-bit number subdivided into four bytes

.

What is my private IP?

Private (internal) addresses are not routed on the Internet and no traffic can be sent to them from the Internet, they only supposed to work within the local network. Private addresses include IP addresses from the following subnets: Range from
